    EXAM AND DISCUSSION QUESTIONS

    1. How has the Munsell color system been adapted for display screen color specification?

    2. What is the relationship between bit planes and the number of colors possible on a CRT monitor?

    3. How is it that we see objects as the same color under different sources of illumination?

    4. Explain the relationship between physical, perceptual and CRT color specification schemes, and give examples of each.

    5. Explain the meaning of the term "gamut", and the problems which occur because of differences in gamuts between different display devices and media.
