Funny. I made up my own species- called Skyborns, but I only ever draw one. My own Skyborn oddball named Kateri. I figured I'd redraw the two I used before to explain their genetics. Skyborns can any sort of colors you can think of, and it can be explained. Most common being the yellow-based greens, then their uncommon white-based blue cousins. All other colors are due to some sort of mutation with their 3 primary colors and other factors. Bleh.
