I think this is awesome. Congrats on getting it in TPT.
One thing I need to ask though is if GOLD glows? If it does, how do you get it to glow?
If it doesn't, I was thinking that we could give SOAP a use. Whenever SOAP touches GOLD, it causes GOLD to glow or shine, like it has been polished. :)
Edit:
Also, considering how new GOLD is and how this change will only affect colors properties and not reaction properties, it won't break any saves.
I think I should make a thread on this...
Its in the official version now
