MTX Dyes showing up weird in dungeon

I have I think the "shimmering chocolate" dye. In my house and around town, it looks normal. Just went to heroic snake pit and it looks like diarrhea. Pics here: https://imgur.com/a/6XE4fdJ

Some dyes have dungeon colours ;>

black coffee looks like seafoam green on the char screen. but looks black with white outlines in the caves. shimmering purple and shimmering blue looks normal in both. so it might not be a bug but a graphics rendering issue.
