I'm looking for information on color science and computer graphics. 1) Could someone point me to software which converts between the various color systems? For example, from "dominant wavelength, purity, reflectance" to RGB? How about between the Munsell colors and RGB or XYZ? How about software which runs on, say, a Sun lets you navigate around the different 3-d color spaces? 2) How about equations to provide the xy or RGB values for various black body temperatures (when they say that a "G" star is yellow, I'd like to be more specific....) 3) Where would I find specifications on the gamuts of specific color monitors or tv sets? Are they all about the same, or is there significant variation? 4) How would I calibrate a monitor? What do the "hue", "saturation", etc knobs really do? 5) As I understand it, the color palatte of the IBM CGA standard is really limited to 8 colors with 2 intensities of each. On the other hand, the EGA standard allows for a "64 color palatte". Which 64 colors? 2 bits per primary? 6) What are good reference books for questions like these? Thanks a lot for any help! -Neal McBurnett, ihnp4!druhi!neal
