>>10369267Yeah, I believe actual Lego plumes are made from a softer plastic like polypropylene and it sounds like that doesn't take the dye, according to your experiments. I was dying Chinese bootleg feathers that only come in white, and they are made from rigid ABS that can be dyed with enough effort. However, they expand just enough to no longer fit in the helmet holes. If I do the dyed approach again I'm going to try an idea I have that might help. I'll follow up at some point in the future, maybe!
