An idea, works for Vanilla Minecraft too.

A great advantage to Minecraft is the access to hundreds of thousands of Texture packs at your disposal. Blocks being retextured in thousands of different ways, depending on the artist. So why, when people make pixel art to submit as, say, a picture, they use wool which is limited to the very main colors? Craftland has fixed that with RGB wool, but it still looks like wool. Why not take it a step further? Why not recolor every block in a resource pack, and make them all a particular color? It would be great for pixel art, you could have 20 different shades of red instead of 1. Just a simple idea I wanted to put out there. Have a good day.
