he somewhat drab coachlacquers of yesteryear and the

unbelievable diversity of modern carcolours are a century – and worlds!– apart. Black, red-brown and green

were the big sellers in the old days.Other shades were neither availablenor affordable. Today, Standox alone offers well over 30,000 shades– with different effects and in diffe-rent paint types. More than any carpurchaser, today’s vehicle refinisher

is faced with a seemingly endlessarray of colours from which to accu-rately identify – and accurately tint – the desired shade. The refinisher’schoice ultimately decides whether heand his customer are truly 100%satisfied with the finished paintwork.

The world of colour

What is colour?

Colour is basically nothing other than a (subjective) sensory impres-sion on the eye. Colour is a propertyof light and is entirely dependentupon it.

What is light?

Light is electromagnetic radiation ofvarious wavelengths. The range oflight visible to man can be brokendown with a prism into the colours ofthe rainbow or of the spectrum, fromred through to violet.

How does colour come about?

To perceive colour, three things arenecessary.

● A light source

● An object that reflects the light

● A receiver that picks up thereflected light (e.g. the eye).

A coloured, e.g. red, surface is per-ceived as being red because it onlyreflects light of the wavelength ofjust this colour, i. e. red. All the otherwavelengths are swallowed up(absorbed) by the surface.

However, there’s no rule withoutexceptions:

A white surfacereflects all the lightrays and thusappears white. Ablack surfaceabsorbs all the lightrays and thusappears black.

The colour reflectedby an object alsodepends upon thecolour of the lightstriking it.

For example, let us assume that agreen object is illuminated by a redlight. This object only reflects thecolour green. Since, however, it isonly illuminated by red light, it reflects absolutely nothing – andappears to the eye not green butblack.

Incidentally, the human eye is inca-pable of perceiving ultraviolet andinfrared light.

The phenomenon of metamerism

It often happens that two colours(e.g. OEM colour/vehicle refinish)appear identical in daylight, but dif-ferent under a different light source(e.g. artificial light). This is known asmetamerism.

Metamerism arises when the pig-ments of two colours differ: If, for

example, one green is based on apure, green pigment, and the othermixed from blue and yellow pig-ments.

Daylight

Artificial light

Can metamerism beavoided?

During vehicle refini-shing, it is essential toonly use the samepigments as employedin the online finish.

Standomix colour for-mulae satisfy this condition. The formula-tions are tested in thelaboratory under awide variety of types oflight. Nevertheless, ifsubsequent tintingproves necessary inpractice, mixingenamels from the spe-cified Standomix colourformula should alwaysbe used if possible.

The A to Z of colour

Absorption = The take-up

of light by the illuminated

object.

Additive colour mixing = The

addition of light of different

wavelengths. E.g., red and

green light yield yellow light

(on the colour TV principle).

Colour = Physically (and ana-

tomically) dependent sensory

impression.

Infrared = (IR) light with a

wavelength of > 800 nm.

Light = Electromagnetic radia-

tion in the wavelength range

of 400 nm (blue) to 800 nm

(red).

Metamerism = Apparent

identity of two colours under

the same light source. Other

light source may yield other

colour impressions (due to

different pigments).

Primary colours = Red, blue

and yellow (see “Subtractive

colour mixing”).

Reflection = The return of

light from a surface.

Secondary colours = The sec-

ondary colours are the three

colours produced by mixing

two primary colours, i.e.

green, violet, orange.

Spectral colours = All the

colours perceptible with the

human eye, with an electro-

magnetic wavelength range

from 400 nm (blue) and

800 nm (red).

A perfect match?

Ormiracle massproduction.

A few gifted individuals are said tohave what is known as “perfectpitch”. This means that they can pre-cisely identify and strike a note

without resorting to a reference note.By comparison, there have neverbeen individuals with a “perfectmemory of colour”.

The perception of colours is primari-ly a matter of subjective impression,which can be strongly influenced byexternal circumstances. When itcomes to reproducing colours, bind-

ing colour standards and tests aretherefore indispensable.

Precise colour tests and releases have been routinely practised inpaint production for decades. Uni-form, efficient final inspections ofcolours would in fact make sense inall mass production processes. Thisway it would be possible to ensure


The application methods employed,the paint types used and the differentformulations from different paint sup-pliers also have an effect on colouraccuracy.

that original colours remained stablethroughout a production batch, i.e.without colour fluctuations.

The reasons for colour fluctuations,e.g. in the OE production ofmodern vehicles, are varied. Oneonly has to consider the huge rangeof colours (plus the special colours as well), which are specified for all

of a manufacturer’s new vehiclemodels! – although the individualmodel series are produced at diffe-rent sites.

To make matters worse, paint is oftenapplied with different applicationmethods (manually, automatically byrobot or electrostatically) or eventotally different paint bases are used

(e.g. conventional/water-basedpaint). Car production plants are justas frequently served by changingpaint suppliers, who all operate withtheir own totally different formulae.

New colours –new demands

When today’s designers for theOE production of cars developnew shades, a huge and evergrowing diversity of demands andspecifications have to be compliedwith. Because every new colour isexpected to

● suit the vehicle shape and har-monize perfectly with it,

● slot neatly into the colour line ofthe particular vehicle segment,

● satisfy certain pigment require-ments (e.g. for industrial safetyreasons),

● meet technical demands(e.g. resistance to fading),

● comply with the estimated costs,

● be easy to apply online,

● convey individuality (demarca-tion from the competition as wellas a means of differentiation forthe customer),

● take up current fashion trends,etc.

Colours composed by designers withtotally new pigments and effects aretherefore by no means rare, givensuch a huge range of specifications.

And in all this the demand of service-ability is very often neglected –particularly when it comes to simpleand trouble-free repairs for thevehicle refinisher.

From the OEM colourto the Standox colour formula

New colours mean new tasks. Standox colour formulae consistently adhere

to the principle of easy colour reproduction.

Clear, sensible search criteria – car colours

have to be identified quickly and accurately.

No less important is finding the right mixing

formula for the colour in question. And including

correction instructions.

Nothing is impossible.

“It must be easy for anyone likeStandox with a gigantic colour for-mula archive to produce formulaefor new automotive colours!” Never-theless, the new standard productioncolours may differ immensely.

ing simple, a principle which youare also strongly advised to follow indaily practice. Wherever possible,use only the mixing enamels of theStandox colour formula – even fortinting work. Otherwise colour varia-tions and metamerism may occur.Anyone who adheres to this principleis on the sure road to success.

Aggressive environmental conditions, e.g.

omnipresent UV radiation, can modify even the

most stable shade. Nevertheless, if the paint-

work is ever damaged, the vehicle refinish

colour must still exactly match the automotive

paint. Standox Coloristic experts therefore

study and document colours day after day in

practical conditions. This also helps to ensure

that you can always benefit from our latest

findings.

There is now a growing trendtowards extensions of the colourrange through the addition of totallynew effects.

For this reason it is necessary tometiculously develop each individualformulation from scratch.

At Standox, the overriding principleis to make colour mixing and match-


It certainly takes a little experiencewhen it comes to looking for – andfinding – the colour code numberdetails on a damaged vehicle.

These type plates, which supplyinformation not only on the originalshade, are affixed by every manu-facturer in a different position on thecar. And this position may even varyfrom model to model as well.

Trouble arises if

● colour codes are missing,incomplete or simply incorrect(which can also happen!)

Accurately identifyingcolours

You can always ring up yourStandox representative or Standoxdistributor or cast your eye over theUNIVERS system (see page 15).Thanks to regular Coloristic updates,you can be sure of always havingthe very latest helpful information atyour disposal.

● code numbers have beenchanged in the factory. (This isoften done if contrast colours foradd-on parts or interior colourshave to be coded as well.)

10

A systematic approach helps to prevent mistakes.


3. Always check whether there isany reference to variants on theswatch fan. If not, then you’ve suc-cessfully identified the right colour.Proceed with point 5.

4. If variant information is provided,you must always take out the variantfan (part of the Color Box) and com-pare the relevant sample again withthe vehicle’s colour.

5. Now that the shade has beennarrowed down, you can select theappropriate Standox mixing formula:Either on microfiche, or with the aidof PC (UNIVERS) or weighingsoftware.

That’s all there is to it. This is thequick and sure way to find thematching Standox colour formula.

Please bear in mind that in allStandox formula documents therequired details are categorizedby manufacturer. The manufacturercodes are in alphabetical ornumeric order.

11

As a rule, five systematic steps areall it takes to find the right Standoxcolour formula.

At any rate, Standox provides youwith all the key data – be it onmicrofiche, for PC scales or throughUNIVERS.

1. Find the car maker’s colour codeon the vehicle (useful searchadvice is also contained in the user’smanuals).

2. Look for this code number in theStandox Color Box and compare thecolour sample on the colour swatchfan with the vehicle’s colour.

No more than 5 steps to the right colour formula

By referring to

your colour sample

you quickly and

easily arrive at the

right shade.

The Standox colour formula

All roads lead to Rome, so they say.At the same time, the surest wayto reach your destination is to read a map.

The situation is no different with theStandox colour formulae, becausehere, too, it is a question of knowinghow to read them. And this is a gooddeal easier than reading a map.

Anyone who wants to read a maphas to understand the symbols listedin the key. This is a simple matterwhen it comes to Standox colour for-mulae, because you are helped inyour work by instructive pictograms.This is all made easier by the factthat Standox has confined itself tothe truly essential details – and sticksto the same layout throughout.This means you can get on quicklywith your work.

On the preceding pages you learnedhow to accurately identify colours –and arrive at the matching Standoxcolour formula.

On this and the following page wehave presented several formulae, allwith identical layouts. It thereforemakes no difference which informa-tion medium you use. The searchpaths, symbols and other featuresremain the same.

Not some esoteric science.

Times change.So does the system.

Any vehicle refinisher who back inthe 60s ordered “Mars red A3A”from his paint supplier, received aready-mixed paint. However, in thosedays the paint often took a long timeto arrive, particularly if out-of-the-ordinary colours were requested.

Standox was one of the first tounderstand the signs of the times andestablished a modern system oflogistics which rules out “deliveryperiods” from the outset: TheStandomix mixing enamel system.

Standomix is effectively a miniaturepaint production plant for you, theuser. You determine the paint typesand shades by referring to theStandox colour formula.

During the changeover in thelogistics system, use was then madeof an information technology, whichis still used today in the vehiclerefinishing trade: Microfiche display-ed on a special reader. AlthoughStandox still serves microfiche users,the days of this technology areclearly numbered.

Complex weighing systems andother, labour-saving PC softwareprograms, which support job man-agement, are becoming more andmore widely established.

The right system

The Standomix mixing enamel system.

There’s hardly a quicker or simpler way of

obtaining the right refinish colour.

Microfiche readers are still in use, although they are increasingly being superseded

by efficient PCs with specially developed software (UNIVERS, see page 15).

access to all current colour formulae,but also supplies specific answers tovirtually all questions which arise ineveryday business.

UNIVERS offers paint-related infor-mation on a CD-ROM: Mixingformulae, colour and product infor-mation, safety data, applicationinstructions and much more besides.Its structured search, help and crossreferences between individual partsof the program have eliminatedtime-consuming rummaging throughinformation in piles of paper or onmicrofiche and floppy disks. All theUNIVERS data can be printed outany time and as required.

UNIVERS.All the information at a click.

UNIVERS is far, far more than a re-ference work. For instance, it enablesStandox mixing formulae to be modi-

fied as required and stored for cer-tain specific customers. In addition,notes and other remarks can also beadded for each shade.

If desired, UNIVERS can also showfor each mixing formula the smallestquantity that can be efficientlymixed. This information is particularlyuseful and helps to cut costs whencolour samples or spray-out cardshave to be produced.

The quantity of organic solvents(VOC values) can also be quoted foreach mixing formula. A VOC calcu-lation method for ready-to-spraymixtures (including hardener andthinner) is in preparation.

UNIVERS will soon be extended toinclude extra performance features,which UNIVERS users will auto-matically receive with the regularupdates:

● In addition to the currently sup-ported electronic scales Sarto-rius PMA 7200 and Mettler 7100,further weighing systems are now being included.

● Additional interface for Internetaccess.

● Additional interface for the inte-gration of GENIUS, the Standoxcolorimetry system.

Further extensions, e.g. for warehous-ing and inventory management, arealso in preparation.

What makes GENIUS especiallyingenious is its ability to correct for-mulae. Whenever the measuredshade differs from the online origi-nal, the software developed byStandox modifies the stored formula.

Since each modified formula canbe deposited in a customer file, thestock of formulae is constantlyexpanding. This means that an addi-tional spectrum of variant formulae issoon available for dealing with eventhe slightest shade deviations.

Each refinishing job starts with iden-tifying the colour right. You can findout about this on pages 10 and 11.

Step 1Using Standox Polishing Paste, cleanan area about the size of your palmnext to the damaged paintwork.

Step 2Look for the colour code and thecolour designation on the car. Makeabsolutely certain that the vehiclehas not already been resprayedbefore.

Step 3Take the Color Box swatch fan (orvariant fan) to the vehicle and com-pare the fan’s colour sample with thecleaned surface on the vehicle (seeStep 1).

Step 4After identifying the shade, look forthe corresponding mixing formula inthe PC, on the computer scales or onmicrofiche. Mix the exact quantitiesof ingredients as given in the for-mula.

Step 5Carry out a colour check, first of allas a rough comparison. Best of alluse a spray-out card. In the case ofconventional solid-colour paints andStandohyd solid-colour/metallic/pearlescent basecoats, apply thepaint to a Standox spray-out cardand allow it to dry. In the case of con-ventional metallics and pearlescents,make a rough comparison by lettingthe unthinned paint run off themixing stick. Colour tests should be

carried out if possiblein daylight (northernlight) or in artificial light,e.g. OSRAM LF 72 orPHILIPS TL 96.

Step 6If the colours match,prepare a spray-outcard for a precisecolour comparison –and paint the vehicle.File away the card asdocumentation.


20

Use the 2-gun principle

Advantages of the 2-gun principle:

1. Time savings... as a spray-out card for the nextjob is produced together with thevehicle refinish.

2. ReliabilityWith metallic and pearlescentspray-out cards, the effect of thespraying technique has an effect on the shade.

3. Savings of time and money!Efficient working methods eliminate paint defects and un-necessary spraygun cleaning.

Prepare thepaint sample forthe next vehicle.

Shade OK =finish paintingthe vehicle.

● Antiquated formula docu-ments or data carriers.

● Choice of wrong shade.

● Failure to adhere to stirringtimes/intervals.

● Dirty mixing lid spout: Smallquantities cannot be accu-rately weighed.

● Change of can

● Stirring: By hand with a mixingstick – then 10 min in the mixer.

● Wrong or incorrect light whenmatching colours – Standoxrecommends, for instance,OSRAM LF 72 and PHILIPS TL 96lamps.

Possible sources of error when mixing colours

● Dirty scales.

● The scales are in a draught.

● The scales are not standing firmly.

● The microfiche reader is dirty,causing mistakes when copying down the data (use of wrong mixing enamels, wrong product quantities).

The causes of error are as varied as the colours themselves. Here is a selection of the most frequent error sources.


21

What about your mixing station?Everything OK?

The success of each job alsodepends on the state of your work-place.

Only when you have truly ensuredthat everything is in its place and inproper working order can you savetime and money. Only then can onework efficiently.

● Regularly clean your equipment,mixing lids and tools.

● Regularly check your equipmentfor correct function – particularlyyour scales.

● Make sure that you are alwaysworking with the very latestversion of the formula.

● Accustom yourself to a certainstrict routine when it comes tostirring the paint. For instance,always mix for 15 minutes beforestarting work in the morning andtowards midday. If you are usingnew cans, these first have to bestirred manually and then mecha-nically for 10 minutes. And beforeweighing paint quantities, alwaysstir for a minute.

Developinga keen eye

In spite of following all the rules and steps, and in spite of referringto the possible variants, it may stillhappen that the mixed colourdoesn’t exactly match the car’scolour.

Just how varied the causes of colour differences can be is descri-bed in detail on pages 6 and 7.

In such cases, the new colour has tobe tinted. As there are no fixedformulae for this, experience and atrained eye are all the more impor-tant.

But don’t worry: There is a wholerange of useful rules even for tin-ting. Anyone familiar with them iswell on the way to mastering thistechnique.

For tinting especially, spray-out cards are of decisive importance (see also page 18, step 5).

Tinting made easy

22

Basic rules

● When tinting, only ever use the mixing enamels specified in the colour formula.

● When tinting an existing colour, follow the principles of colour complementarity and affinity as presented in the chromatic colour circle. Complementary colours are not recommended for tinting as they introduce incompatible pigments into the new colour, which may result in a muddy final shade.

Spray-out cards

● Spray each colour sample immediately.

● Colour samples should be applied to one andthe same card without gaps in between.Try to avoid mixing the individual samples.

● All colour samples should be the same sizebecause size is also an important factorin assessing a colour. Sufficient are areas ofabout 4 x 5 cm.
