Silent Strider submitted a new mod: Color Wheel - Change the hue of blocks Read more about this mod...
Looks cool. Would it be hard to implement something similar, but for clothing and/or furniture items too?
I'm not sure it's possible. Blocks have a simple way to shift their hue, one that works for all blocks, even those added by mods. Clothing and furniture, to the best of my knowledge, can only be recolored by manually replacing every used color with another, which needs to be coded on a per-item basis.
