In February 2015, Helm started a topic on color balancing Pixel Art on Pixelation. A wish was expressed how it would be nice to have a plugin for Cosmigo's Pro Motion which could do color balancing. I had look-into-Pro-Motion-plugin-development on my things-I-would-like-to-try-sometime list for some time already so I took this opportunity to develop a plugin like that. The result is presented on this website. The initial version did not attempt to preserve the brightness in the output but after Ai and DawnBringer kept going on about how useful brightness preservation is, I implemented an optional brightness preservation strategy as well.
