So, basically like what already exists, but with the ability to make the different nodes different colors and a variety of options for how to apply them. I'm gonna say the reason I didn't find the "Edit Colors" option before is because the lack of definition against the walls of the shower made it illegible.

Still gonna stick with this, though! The alternate transitions between colors would be pretty cool!

I mean, yes, you could just make your custom dragon fluffy, but It's not a default species! Presumably, the fluffy dragon would be a new default species that you could then encounter, and adding it would introduce a handful of new anatomical options for your dragons, like special dragon ears!
