9mm, 3/8 acrylic source for colored acrylic

[Treehrtsme]

I know you can get clear, white, and some forms of black and 3/8, but I've heard of colors like gray and orange in 3/8 thickness but I've never been able to find a source. Does anyone know anything about this?

I use professional plastics, i know they at least have grey. Not sure on orange though.
