Colour

Psychophysics of coloured light

1. Viewing light in the absence of objects
2. Cones
   • linearity
   • metamerism
   • mesopic light levels: rods
   • colour deficiency
3. Colour matching
   • `all else being equal'
4. Opponent colours

Colour appearance in colour images

1. Influence of viewing conditions on colour judgments
2. Constancy
   • Boynton's basic colours
   • television engineering
3. Contrast
   • special role of edges

You will notice that my notes for this and the previous lecture are scanty. The problem is that I know too much about these subjects to write notes that are concise enough to be useful to me. I am in the process of writing a non-scanty version, which you can find here.
