color & light

color is the result of light…different types of illumination—sunlight, twilight, candlelight, strip lights—create different color effects

•shadows•time and weather•luminosity•iridescence•luster

all are different lighting or surface conditions that ultimately influence the color that we see

attention to these details is vital—ask yourself what your material selections will look like in different conditions

shadows

•created by the absence of light•solid objects cast stronger shadows

shadows

time & weather

time of day—sunrise, morning, noon, sunset, night

season—spring, summer, fall, winter

weather—sun, rain, sleet, mist, snow

location—Southwest, Arctic, tropics, city, country

luminosity

the ability of a color to give a glowing impression

• seen as the effect of sunlight or snow

• seen in translucent objects• water, sky, sunsets, certain

flesh tones, glow of silk…

luminosity

luminosity

iridescence

a shimmering impression•opals, mother-of-pearl, soap bubbles, butterfly wings•caused by interference of light—refraction or diffraction

luster

impression given by subdued light•silver more lustrous than pewter•silk or satin more lustrous than felt•polished wood more lustrous than unfinished wood

color and light

color is the result of light

different types of illumination—sunlight, twilight, candlelight, strip lights—create different color effects

different lighting conditions affect hues in many different ways

color temperature:

•way of describing the degree of whiteness of a light source

•sources that produce a bluish white light have a high temperature color•sources that produce a yellowish white light have a low color temperature

color temperature:

Kelvin—TECHNICAL DEFINITION—as a piece of metalis heated, it changes color fromred to yellow to white to blue-white

color temperature:

color temperature:

daylight— •quality of light is intense and includes the complete color spectrum•in daylight your material will be able to reflect its own special hue of the spectrum

•sunlight is ayellow-whitelight—just looks yellow in comparisonto the blue sky

color temperature:

daylight:

•daylight is blue white because it is a combination of sunlightand bluish light from the sky•blue white light is bestfor reading true color but not great for skin tones

selecting colors intelligently

•be sure to look at all surface colors (carpets, walls, furniture, etc..) under the lamp color specified, as well as daylight•show clients color board under both sources

participation activity:color boarddirections:…using the materials in the resource room, create a color board for a room of your choice…explore one or more of the following lighting conditions using your board:

•shadows•time and weather•luminosity

…write a 2-3 paragraph summary of your exploration and include this with your color board in your portfolio …example: paragraph 1—your aim & technique/protocol

paragraph 2—your observationsparagraph 3—changes you would make
