|I would take because shadow magenta + any brass dye. Fits better to the back item|
|You should set some kind of goal for yourself - what do you want to accomplish with the colours? Because "good dye ideas" is too broad and hard to tackle due to that.|
The thing that stands out the most to me on your character right now is the wings, so it'd probably be important to try to incorporate colours from those (gold, pastel purple and blue) if you want to look cohesive.
|I'm not sure I'd keep the wings on a thief look as that does kinda limit your color options. Still, if you kept it yellows, oranges, and purples wouldn't be out of order.|
