What does two different colored eyebrows mean?

Having two eyebrows of different colors, a condition known as eyebrow color heterochromia, results from an uneven distribution of melanin—the pigment responsible for our eyes, hair, and skin color. This difference in pigmentation can arise from various factors, including genetics, injury, certain medical conditions, or as a natural aging process. In most cases, it's a harmless variation that doesn't negatively impact overall health.
