Every now and then when I go into minecraft, all the characters created in the character creator look just fine, except they have brown hair and blue eyes, like Steve's. What is interesting is that the shape of the gate and the eyes did not change, only the color. I'm sorry but I don't know why this happens, it just randomly happens to me when I enter minecraft, but mostly it happens to me when I enter minecraft preview, I'd love it if someone who also has this can write in the comments.
