Gray
A steel blue-gray eyeGray eyes have less melanin than blue eyes, even though they are considered a darker shade of blue (like blue-green). They are most common in European Russia, Finland and the Baltic States.[citation needed] Under magnification, gray eyes exhibit small amounts of yellow and brown color in the iris.
A gray iris may indicate the presence of a uveitis. However, other visual signs make a uveitis obvious.
Visually, gray eyes often tend to appear to change between the shades of blue, green and gray; this is because gray eyes are extremely light, as mentioned before. The color change for gray eyes is usually influenced by the lighting and the colours in the surroundings (such as clothes, makeup, etc.).
The Greek goddess Athena was renowned for having "owl-gray" or "sea-gray" eyes (in Greek, γλαυκῶπις glaukōpis).[30]
