Recently for a while now, I've been debating for a long time now on what 白 (white, clear) is supposed to depict. I've heard from a lot of sources that it could be either a rice grain, a thumb, an acorn, candle light etc.
The thing is, I cannot determine what this character is originally supposed to represent.
I did research on my own figuring out what this character depicts and in my opinion, I think it might possibly depicts a human's skull noting the character's use in 皃 since in that character, it was used to emphasize the face/head of a person. I also took note that it was almost similar to 囟 in ancient form since they seem to share the same shape expect 囟 had a vertical line through it. However, when looking at the old Chinese pronunciations for 白 and 囟, they were completely different. So I'm doubting that it probably depicts a stylized human skull.
If anyone can, some help on finding the origin of 白 would be nice since I cannot come to a conclusion on what this character is supposed to be.
