Clip3: Variation of color proportion and brightness over time (Apr. 15, 2003) clip1, clip2, clip4

- In some bright colors like 'white', there is a clipping on brightness. (See the square 5 and 6)
- Color proportions are distorted by illumination changes more in bright colors than in darker ones.
- It would be good to see the plots of the weighted color deviations from the nearest codeword.
