1. INTD 53 color interactions

2. after images all hues have after images affect adjacent colors, especially white— white surrounded by hues cannot easily remain white the result of color seeking its opposite adjacent hue tinged by its complement

4. successive contrast afterimage reaction when eye views colors one after another positive—same as color viewed negative—complementary hue of color viewed

5. successive contrast

11. outlining in black or white reduces or stops the afterimage effect

12. successive contrast

16. middle grays or neutral colors—most strongly influenced values become tinged with complement of hue make adjacent hues appear stronger smaller gray area more strongly influenced

17. simultaneous contrast eye requires complementary hue of any color it sees—imposition of color onto adjacent area of color

18. simultaneous contrast concerned with interactions that occur between hues, broken hues, and neutrals outlining halts simultaneous contrast

19. simultaneous contrast achromatic—concerns itself with black, white, and grays gray—darker on light background, lighter on dark background light values appear lighter on dark background value surrounded by lighter background appear darker

20. simultaneous contrast chromatic—concerns itself with hue changes due to surrounding hue influence one color appears as two if placed on two different background colors two different colors appear to be same if placed on two different carefully chosen backgrounds (yellow & red background—yellow-orange on yellow & red- orange on red)

21. bezold effect Wilhelm von Bezold (rug designer)—alter entire appearance of rug design by simply changing single color

22. optical mixing result of two or more colors mixing to “become” another color divisionism—separate colors set side by side so eye can blend or fuse them

23. optical mixing pointillism—when dots of color are used on a white background

24. optical mixing— pointillism to achieve good results: consider munsell color wheel—colors side by side value of hues employed intensity of hues employed quantity of hues employed viewing distance lighting conditions

25. participation activity: optical color mix …using the bezold effect, divisionism or pointillisim, create an illustration of your chosen optical color mixing strategy …you may use paint, markers, colored pencils, magazines, etc… to create your illustration …image outlines will be provided if necessary
