dyed ahoge

A character's ahoge is colored differently from the rest of the hair. The second color has to dominate the majority of the ahoge, rather than just the tip. If that happens, use colored tips instead. If the ahoge's color is also present in the rest of the hair (Danbooru post #4936595), just use two-tone hair and/or multicolored hair.
