1 Ch. 19 - Light II. Light and Color (p.528-535) Light and Matter
Seeing Colors Mixing Colors

2 A. Light and Matter Opaque absorbs or reflects all light Transparent
allows light to pass through completely Translucent allows some light to pass through

3 B. Seeing Colors White light contains all visible colors - ROY G. BIV
In white light, an object… reflects the color you see absorbs all other colors REFLECTS ALL COLORS ABSORBS ALL COLORS

4 Stimulates red & green cones
B. Seeing Colors Stimulates red & green cones The retina contains… Rods - dim light, black & white Cones - color red - absorb red & yellow green - absorb yellow & green blue - absorb blue & violet Stimulates all cones

5 Test for red-green color blindness.
B. Seeing Colors Test for red-green color blindness. Color Blindness one or more sets of cones does not function properly

6 View Java Applet on primary light colors.
C. Mixing Colors Primary light colors red, green, blue additive colors combine to form white light EX: computer RGBs View Java Applet on primary light colors.

7 View Java Applet on filters.
C. Mixing Colors Filter transparent material that absorbs all light colors except the filter color View Java Applet on filters.

8 C. Mixing Colors Pigment
colored material that absorbs and reflects different colors Primary pigment colors cyan, magenta, yellow subtractive colors combine to form black EX: color ink cartridges

9 C. Mixing Colors Light Pigment
When mixing pigments, the color of the mixture is the color of light that both pigments reflect.

11 Negative Afterimage - One set of cones gets tired, and the remaining cones produce an image in the complimentary color.
