The ⚪ White Circle emoji is the opposite pole of the ⚫ Black Circle. It symbolizes light, purity, brightness, or even a patch. Dermatologically, white spots suggest a skin deficiency or any other deficit (in the absence of a birthmark or other underlying conditions, ofc).

This emoji looks like a 🔵 Blue Circle but has a white color. Its meaning may be different depending on the imagination of the user however one of the common meanings it has acquired is a symbol for asexuality (i.e. absence of sexual attraction to anyone) and genderlessness (i.e. refusal to belong to any gender).
