1. COLOR, FORM, AND DISTANCE

2. COLOR  The color of an object is determined by the wavelengths of light that object absorbs and reflects.  When you paint an object, you are applying a pigment that selectively absorbs and reflects different wavelengths.

3. COLOR  Color is an illusion. Your brain tells you that things have color. All color wavelengths are absorbed except those wavelengths that produce that color.  Ex. If you see a wall painted red, all wavelengths are being absorbed, except the red wavelength.

4. COLOR SPECTRUM  The color spectrum is easily remembered with the acronym ROY-G-BIV from the longest to shortest waves (red-orange- yellow-green-blue-indigo-violet)  Red-Orange-Yellow-Green-Blue-Indigo-Violet (longestshortest)

5. WAVELENGTHS  There can be a broader wavelength than red, but we can’t see it  Ex. Radio waves.  There can be a thinner wavelength than violet. But we can’t see that either  Ex. Microwave or ultraviolet waves

6. TWO THEORIES OF COLOR VISION  Trichromatic Theory: The human eye has three types of cones (red, green and blue) and thus all color perception must be due to mixing of these three colors.  Uses red, green and blue in staggered forms. This is how a TV works (red, green, blue projectors).

8. COLOR VISION  Trichromats- People with normal color vision who can discern all the colors of the visible spectrum- red, green, and blue-violet- as well as colors formed by various combinations of these hues.  Monochromats- People who only see in black and white  About 1 in every 40,000 people  Dichromats- People who lack one of the 3 types of cones, making it difficult to distinguish between certain types of colors.  People who are colorblind (red-green most common in men 8%; 1% in women)

9. TWO THEORIES OF COLOR VISION  Opponent-Process Theory: Colors are paired and are antagonists (red vs. green, blue vs. yellow, white vs. black).  If a cone is responding to a red wavelength, it cannot respond to a green one at the same time.
