The mod works fantastically, and I get the aesthetic purpose of keeping the golem copper like when it slowly stops working, but a more truth version of the minecon would be a texture more similar to the actual oxidized copper in game

Ah thanks for pointing that out. In my opinion is looks pretty close, but I'm colourblind to green so I might not be the best judge. >.>

No problem, I did a custom resource pack yesterday. The colors are fine but I messed up a little bit with the shadows on the back. And now that we are at it, the oxidized button ITEM texture is the same than the weathered button. The block is fine.
