Freetone – Pantone-ish colour palette for Adobe products
I'm not sure how helpful this is?
The service Pantone provides is not really a list of colors. It's the calibration of almost every printer and item that can create color, in every medium and on every surface, against their color library. Not just printable colors either, also things that can't be printed like metal and florescent colors.It means you can get a book cover and a business card printed, some plastic injection molded, have your car painted and be assured they are all going to be exactly the same color when they arrive.
It's the mapping between pantone names and the real world that's valuable, and this doesn't seem to help with that.
