Allows use of a color ramp consisting of a list of selected colors. Currently there's no way in QGIS to classify a renderer using some list of colors you've previously selected. So you can modify the colors manually after classifying, but that's a pain if you're regularly using the same color scheme. Basically, it's like the color brewer color ramp options but allowing users to pick their own preset list of colors to use* (Because Cynthia Brewer isn't the only cartographic color expert!)
