Texture dye, what would you like to see?

Just as the thread title says what would you like to see as a texture dye? What I mean by texture is like the dye has a pattern to it, so "Flame Red" would dye your Coat with not just 1 colour but with a flame pattern all over it.

Ideas and thoughts?

I'm not so fussed about patterns as much as a cloth that looks like silk, rainbow silk can we have it?
