I can't do colored molds. Tried it for a while and my ear just got sore/irritated all the time. oh well. I have a red hearing aid, and a dark sienna (almost black) CI processor and I can jazz them both up with nail decal stickers and stuff, so I'm fine with that.
I can also change the color caps on my CI's headpiece too, right now it's red but I also have dark sienna, white, sky blue, teal, and a sandy color.
