I don;t know anyone who create texture "by the numbers".. in poser, you have a color picker,and just adjust the sliders the way to want them. then just save whatever you are working on back out with the new colors.

You can save out materials in P5+, with P6+ you can save out material collections, and with shader spider, you can even save out mat poses for DS, and poser 4+.

You add the colors while in poser, and are looking right at them while you adjust them, so i don't understand what you are trying to accomplish. Trying to change them by hand editing a file in a text editor?

Way too many people take way too many things way too seriously.
