Color Perception
Dimensions of Color:
Hue:
Brightness:
Saturation:
Color Mixture:
Subtractive Color Mixture:
e.g.
Additive Color Mixture:
complementary hues:
Trichromatic Theory of Color Vision: (Young-Helmholtz theory)
S-Cones:
M-Cones:
L-Cones:
e.g. a 450 nm light
e.g.
Color Blindness:
e.g.
protanopia -
deuteranopia -
Tritanopia -
Trichromatic Theory can't explain all color phenomenon though
Opponent-Process Theory:
3 types
Red-Green:
Yellow-Blue:
Black-White:
lateral inhibition creates the opponent process cells
Color Constancy:
