<> According to some literature I recently got from Shima Seiki, they employ the Munsell color system as a part of their paint system. Munsell & Pantone colors are a set of standard colors used in printing & publishing. Beyond that things get a bit fuzzy. Where should I look to find out about how to calculate the color values? YIQ,RGB,CYM,HLS,HSV whatever, for my needs it will end up in RGB. RGB is probably not a good enough representation at 8 bits per primary, but it is what I have at hand. Suggestions? Helpful hints? I have "heard" that they (either) may be a licensed color set, in which case information on where to write would be much appreciated. Why does it matter? Because this is what the people are used to working with, and there is no good reason to presume that a perfectly good artist should be distracted by discontinuity in the design system. If the colors are designed as combinations of for example 16 or so basic inks, than how perfect can one assume inks to be? I do not mean perfect in respect to RGB or even to there names (Magenta for instance :-), but rather how nicely behaved will they be when I mix them? The desire is not to achieve the ideal, but rather the actual. -- Jim Hutchison UUCP: {dcdwest,ucbvax}!sdcsvax!hutch ARPA: Hutch@sdcsvax.ucsd.edu Disclaimer: I'm gone, really, away from my terminal, in the tub, honest.

Munsell Color References: "A Color Notation", by A. H. Munsell "Book of Color", The Munsell Color Company 2441 North Calvert St. Baltimore, MD 21218 CIE and Munsell equivalents are discussed in Keegan, H.J, et al. "Digital Reduction of Spectophotometric Data to Munsell Renotations", Journal of the Optical Society of America, Vol 48, p863 (1958) Display of Munsell colors on an RGB CRT are discussed in Meyer, Gary W and Donald Greenberg, "Perceptual Color Spaces for Computer Graphics", in the 1980 SIGGRAPH procedings.

Let me add one more suggestion. If you can find a used copy of the Ishihara Test for Color Blindess, I recommend it. It's an interesting curosity (not too expensive), and it can engender an appreciation for one's sight. Added note on the colorized `Adams' scenes. If you are local to the Bay Area, I will gladly show and sell anyone my reshoots (this in response to several inquires of availabilty). I use them in talks on climbing all the time.
