Expand color




What's this?

This effect was a bonus in the bottom list of my pack of plugins. Now with the Russian version (thank you @ReMake) it is time to have its own post.


This effect compare the colors of the canvas with the primary (PC) and the secondary (SC) colors. Based on the ratio of the gap the color will be replace either by PC, SC or unchanged. It could be useful to reduce the weight of the image (less colors) and to turn the image in bicolored picture. Just a tool for fun.


Download it!
