The Gamut Mask Tool Overview

This is a free online tool for creating Gamut Masks which aids in refining a color palette. This tool was created by Richard Robinson and is hosted on his site Live Painting HERE. The Gamut Mask can be either printed or taking a screen shot with another free tool Greenshot and saved as a PNG (PNGs have more detail than JPEGs). From there you can easily create a color palette in Photoshop or GIMP (not shown here.)
