When wearing the Axolotl Flippers (Wurt Roseate leg piece) And hitting the cycle view button for her to change color, with some items. (EDIT: shirt items*).the middle part does not change color. I have not checked if this translates in-game. clicking the cycle button again or taking the item off and back on does not fix it.
I went through all the items and these are what I found were affected.
Draconic chest, Berserker's chest paint, Forging chest cover, Inferno's Toga, Tragedienne Costume, Grimy Goblin chest, Minotaur chest, and
Images of those items on Wurt in spoiler below.
Equip axolotl flippers as wurt and cycle view to the wurt with facepaint and lighter color, the middle will be the same color as non-paint wurt.
