yes I think it should. its not to much to ask those guys I dont think. they might tell you its usless but they did it green with plutonium and uranium and orange with goo.
I was going to do more than just GOLD, but I wasn't sure what to do or which elements to pick since I didn't want to break things, and a lot of elements like the ones listed there can already change PHOT color anyway. I'll try to make future elements change photon colors though.
