Green Eyes

[Siely]

Several independent internet sources say that green eyes are the rarest eye colour in the world.  Does anyone know of a respected reference on eye colour to verify this properly ?

Light green or moss green?

Green eyes are often debated as the rarest eye color, but most people would agree that red, violet and gray eyes are far less common. A large amount of melanin is not present in green eyes, which leads to a phenomenon known as Rayleigh scattering, where light is reflected rather than absorbed by the pigment in the eyes, which results in your eyes appearing green. Green eyes are light brown in colour with a yellow, golden or orange pigmentation called lipochrome.

Thank you.

I was getting confused with Hazel eyes which can be largely green apparently.

From the same source:

Hazel eyes

Typically, hazel eyes have a yellowish brown colour with flecks of gold, green, brown and even blue in them. There is a similar amount of melanin present in these types of eyes as in brown eyes, however the melanin is distributed differently, appearing more around the outer edge of the eye instead of the center. It is very attractive to have hazel eyes because they reflect light beautifully. The Rayleigh scattering effect influences the colour of green eyes as well.

An AI response:

Green is widely recognized as the rarest of the main human eye colors. Only about 2% of the global population has naturally green eyes, making them significantly less common than brown, blue, or hazel eyes[2][4][6]. This rarity is consistent across multiple scientific and medical sources, including the American Academy of Ophthalmology[2][6].

However, it's important to note that while green is the rarest among the primary eye colors, even rarer hues exist but are not typically classified as standard eye colors. For example, gray eyes may be even less common than green, with some estimates placing their global prevalence at less than 1%[1][3][9]. Additionally, extremely rare colors such as red or violet can occur, usually as a result of specific genetic conditions like albinism, but these are considered medical anomalies rather than standard variations[3][9].

In summary, green is the rarest common eye color in the general population, but gray, red, and violet eyes are even rarer, though they are not usually included in the main eye color categories[1][3][9].

I don't have green eyes, I've always classed mine as blue but when I read my 3 x gt grandfather's description on his mariner's record, his eyes were described as grey and it set me wondering. My eyes are a dark blue but would they be classed as grey? Having looked it up on the Internet I'm still no wiser! 
All of my family on both sides including grandparents have had blue eyes of varying shades, no way of finding how far back that goes but it's intriguing.
