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.
I’d say my simplest one is I. Not only is his colour scheme mainly black and white (not counting his gums and mouth interior), but his name is also pretty god demon easy as well, it’s just I. He does have 3 colors in total but the black and white are his main colours.
but I do also have my child baby boi. He only has two colors, blue and pink. https://toyhou.se/5845304.baby-boi
All godthings have very limited color schemes, but Kle’jeum’s is the most restricted with only black and white.
