Light-Dark Contrast11. Blacks, greys, whites
12. Monochromatic (blues)
13. Colours of equal brilliance
14. Colour of equal darkness
Cold-Warm Contrast
16. Strongest cold/warm contrast (red-orange/ blue-green)
17. Inversion of above
18. Red-violet seems warm relative to blue
19. Red-violet seems cold relative to orange
20. Checkered composition contrasting cold and warm
21. Cold-warm modulation in red
22. Cold-warm modulation in green
Complementary Contrast
23- 28. Mixture of bands of six complementary pairs
29. Composition in the complementary pair red/green and mixtures
30. Mixture square of two complementary pairs, orange/blue and red-orange/blue-green
Simultaneous Contrast• the effect where contrast between colors is enhanced by the eye. With tight
patterns of complementary colors, such as red/green or blue/orange, the contrast is so strong that it vibrates and is disturbing to look at.
• To demonstrate this phenomenon, stare at a red square for at least 30 seconds. Then move your eyes to white. You will see the color green - its complement.
Simultaneous Contrast
31-36. Each of six pure colour squares contains a small neutral grey square, matching the baackground colour in brilliance. Each grey square seems to be tinged with the complementary of the background. The simultaneous effect becomes more intense, the longer the principal colour of a square is viewed.
37. Three small grey squares, surrounded by orange. Each grey is distinct: first, bluish, stronger simultaneous effect; second, neutral, simultaneous modification; third, addition of orange, no modification.
Colour Agent and Colour Effect
58. Yellow squares of equal size look bigger on white than on black
59. Red squares of equal size look smaller on white than on black
60-71. Combinations showing how the same yellow, red and blue are altered in expression by different juxtaposed colours
Retinal Fatigue• after image: colors are not perceived accurately.
• occurs because as you look at bright colors for long periods, the cones in your retina become depleted and your eye needs to rest for them to be rejuvenated.
Poor Color Memory • unless we see two colors side by side at the same time, it is
difficult to remember slight differences. • If those two colors are placed side by side then we can see the
differences between them
