It was fairly easy. I wrote a program in QBASIC to split out the appropriate HTML to a text file.
The next challenge is accurate color rendering. The cheap HP $400 color laser printer I used produced some rather muddy looking blues. Blue looks much darker on the page than on the screen.
It's too bad some company around here doesn't have color guidance sheets like this professionally printed, color-matched, and sold as part of their inventory, to go along with their RGB lighting products.
