"So, we've ascertained that Pantone works spectacularly well if you're using Adobe Creative Suite. What if you're using Inkscape or the GIMP? Out of luck, I'm afraid. Because it costs money to license palettes from Pantone, open-source graphics applications don't support it. There just plain isn't the money to pay the license fees.
"There's more, of course. What if the color you want doesn't exist in the Pantone system? You've got two options: Pay Pantone to make you a custom color that only you can use (UPS brown, say), or just pick the next closest color that is supported."
