Hey PMC! This is a rainbow girl. This really reminds me of my friend Kohaku_Melon's old skin. I did a rainbow skin earlier, which was a nyan girl, but it used pastel colors. I love rainbows, so I decided to make a rainbow skin. I've seen other rainbow skins on Planet Minecraft, but they seemed very bright so I decided to just do the regular rainbow rather than the pastel rainbow. The palette was a cape that I made. I'm also going to make a contest very soon, and the link will come in the next skin.

I will providing the enlarged palette and the cape palette If you want you can use the cape with minecraft cape mod.
