One of Three fallen angels from a story of mine. Yet I can't think of what colors to use!!!

The first thing you should note is that in this story, angels aren't quite what humans thought they looked like. Like demons, they take on many unique forms. Now then...

After being defeated in heaven, Elohssa was given the Curse of the Body; where his physical shape was taken away. Leaving him locked within a mask resembling his old face. But, like most sealed evils, humans uncovered it; and after numerous owners, it fell into the hands of an antiques dealer... Where it would be put on for the first time by a boy named Cirrel.

By the way, I use the 'he' pronoun, but Elohssa, along with the other two, have no gender.
