• Hazel eyes, green eyes, and gray eyes each owe their unique appearance to varying amounts of melanin in the iris and the way light scatters through its layers. Hazel eyes typically combine brown and green tones, shifting color depending on lighting conditions. Green eyes, which are among the rarest in the world, contain less melanin and display their hue due to the interplay of pigment and light reflection. Gray eyes have even less pigment, causing them to appear silvery or bluish as light scatters across the iris fibers. These subtle differences in pigmentation and structure not only affect color but can also make these eye shades appear to change slightly in different environments.
