00:00Eye color isn't just about blue, brown, or green.
00:03It all comes down to a pigment called melanin inside the iris.
00:07More melanin creates darker eyes, like brown,
00:10while less melanin allows light to scatter,
00:13producing lighter shades like blue.
00:15Interestingly, blue eyes don't contain blue pigment at all.
00:20Instead, they appear blue because of how light interacts with the structure of the iris.
00:25Eye color is determined by multiple genes,
00:28which is why siblings can have different shades.
00:31Even subtle variations in melanin can create hazel, amber, or gray eyes,
00:36making each person's gaze truly unique in surprising ways.
