A rare genetic mutation can make human eyes appear violet
While most people have brown or blue eyes, a rare genetic mutation involving the CYP1B1 gene can produce a striking violet hue by altering melanin production and light reflectivity.
Elizabeth Taylor's iconic violet eyes were the result of a rare genetic mutation affecting the CYP1B1 gene. This condition reduces melanin production, allowing the iris to appear violet under specific lighting through Rayleigh scattering. This is the same atmospheric mechanism that makes the sky appear blue, but here it interacts with a unique iris structure.
