A1.05
Color Vision and Opponent-Channel Mechanisms
Cards in this group · 9
- A1.05.1Color perception arises from the summed response of three cone types
- A1.05.2Color perception is shaped by neighboring colors, not an absolute judgment
- A1.05.3The blue channel contributes least to fine detail resolution
- A1.05.4Color discrimination drops sharply in peripheral vision
- A1.05.5Past the cones, signals are re-coded into red-green, blue-yellow, and black-white opponent channels
- A1.05.6Opponent coding explains why combinations like "reddish green" don't exist
- A1.05.7Color afterimages are caused by adaptive reversal in opponent channels
- A1.05.8Interface color discriminability should be designed along opponent channels, not isolated hue
- A1.05.9Color assimilation pulls small color patches toward the background, opposite in direction to simultaneous contrast
