Any idea how I might do this? I have a swatch set that I got from the yarn company and I want to find a way to digitize it into a form so that customers can see what colors I can make my costume tails with. Its a bit problematic since my yarn has many shades woven into the skien and would variate the color. Yes, it makes my tails not look so flat, but it also creates problems in figuring out how to show the colors in the best way.

I have a scanner and a digital camera. Seems that the scanner eats the yarn hues by washing them out, especially with lighter colors. I want to make sure that I dont cheat my customers regarding the colors available. Someone suggested a colorimeter but I dont know if any of that software will work well on a Linux machine.
