I have produced both Pantone as well as Roscolux color palates
from published web resources for my own use as they are of course
copyrighted. One could do the same with a RAL color palatte that is
widely used in the paint industry. Of course, none of these really make
any sense in printing as one needs appropriate tools to produce the
desired result - they will remain an approximation.
