The original idea is by Moorchid:

Everything about the skin is colored and brighten.

The hair is orange to give it the brightest variant of similar hair color.
The clothes became red to be analogous and complement the hair.
The shiny yellow moon is colored. It is because many cartoony moons are of that color.
I didn't alter the shoes. Because I want the skin hierarchy to go top to bottom.
The eyes are bright green and blue. A nod to the original eye color.
