Yellow demon, lol!
She's got more colors in her human form, though :(
Let's see all the very simple characters ^^. All characters with one or max two colors! Small details like the eyes don't count. It's fine if they have a different color.
oh goodness she might have a little bit too much colors to qualify but she is VASTLY more simple than many of my other characters. She barely has any designs/details on her but that's what makes her so fun to me. She works with what she has and it speaks in volumes
Shoe is one of my current characters, but there's another in my folder (Grip) and four more incoming, all in the same style!
(Highly recommend looking at the profiles to see better art of em )
