ColorOrganizer is a tool for viewing pallets. It was created by Gizmog in 2016.
It can sort palette colours in different orders: from reddest to least red, from greenest to least green, the same for blue to least blue.
Also ColorOrganizer can sort by average and invert a palette. If the mouse is moved over a square it will show the colours number.
(The readme-file that explains how to use it.)
All in all, a cool idea!
