Seems like most people dont really know about this one, and i definitely didnt until recently.***Esc>options>gameplay>Legacy Color Palettes***ALL older color palettes have a hidden variant that can be accessed through the "Legacy Color Palettes" option. the colors are typically brighter or darker, it was caused by some sort of gamma bug many years back, and some people liked the colors it created so DE kept them in through an option. (though i personally believe they should be more accessible)hope it helps, have fun with your new colors.
In today's melee-only Sortie, I brought Wukong and his celestial twin was still wielding a Corinth.
Found out about this when something fell on my keyboard and pressed H. Took me a while to figure out how to fix this.
