Could someone please mail the recent message about using the definitive reference standard box of 64 Crayola crayons (with the built-in sharpener!) in order to generate a new color database to "jones@cgi.com"? It's been purged at my site. I believe the subject was something like "This is pink?". Thanks. -- Mike

Ok. Since there were two people who requested information about this I dug this message up.

Anyway, the MIT-supplied values for named colors didn't look very good on our SONY monitors, either. Therefore, as an X-server developer for my employer, (Tektronix, Inc) it was my responsibility to do something about it. Advised by our human factors folks that "standard" named colors exist, but only for well-controlled color coordinate systems (like CIE, but not for RGB), I sat down one evening with the handiest standard of subjective color names, a box of 72 Crayola crayons. (Believe it or not, over 50% of the colors from rgb.txt were represented.) Using an X-client implementation of the TekColor model, I created the following list of named colors. Appearance on your monitor may vary because of brand, age, and video drive circuitry, but I think you will find it a better match for the average monitor, than the original rgb.txt file from MIT.

Yup; the colors are pretty terrible.... We are working on fixing them (dunno if UWS 2.2 fixes them or not...). MIT R4 has a better color data base, which you could easily install.

The available reference (which someone else posted already) was based
on the 72-crayon standard (a later ANSI rev than the 64-crayon
standard), but I think it will still serve your purposes.
The ISO 497-crayon standard is still in committee. The French
delegation raised objections to the standard pronunciation of "mauve",
so it may be a while longer. In the mean time, the 72-crayon box is
useful, lighter weight, fits in a more regularly-shaped box, easier to
keep sharp, less costly at replacement time due to meltdown or
teeth-cutting/cat-chewing, and universally available. Even though
it's not an International Standard.datri@concave.uucp (Anthony A. Datri) (01/12/90)
