(Anon with the purple/blackish ranged dragon here The dragon is Mulberry/Midnight/Rose)

I will have to go back and double check :D Since I am pretty sure that it is like stained, the color underneath will change the color we see...

Just tried it and it seems to be one of those colors that can be either Yellow OR green. It looks like a yellow that is heavily tinted with green to me now that I have actually looked at it for more than two seconds.
