#白 is listed under its own radical 白. My dictionary says it is a pictograph but it lists 3 different theories regarding what 白 is depicting. One is a thumb and its nail, another is a scull and the other is an acorn. I can’t picture any of them! Can you?
Anyway, the most important thing I think is that you put only one stroke inside the box. If you put 2, it becomes 自 which means “self.”
