The Visual System: Color

• Color Matching in a Monochromat.  Examine how color matching operates in a person with just one type of receptor, like us at night.  Do they really have color vision?
• Color Matching in a Dichromat.  Now examine how color matching works when the person has two classes of receptors, like a red-green "color-blind" person.  Do they have color vision?
• Trichromatic Theory.  How does the trichromatic theory work.
• Color Aftereffects.  Experience color aftereffects, singly or in pairs.  You can pick the colors.
• Color Vision Theory.  An interactive illustration of the operation of the interplay between the cones which are trichromatic and the color-opponent stages of the visual system.
  • Color Vision Theory and Aftereffects.  How does the combined trichromatic and color opponent theories explain color vision.  Change the adaptation and see how different a white stimulus appears to to the color vision theory interactive illustration used above.
• Dichromacy.  Remove a cone and see what happens.
  • Color Vision Theory and Dichromacy.  How does color vision theory explain the impact of dichromacy.
