The appearance of blue, green, and hazel eyes results from the Tyndall scattering of light in the stroma, a phenomenon similar to Rayleigh scattering which accounts for the blue sky. [5] Neither blue nor green pigments are present in the human iris or vitreous humour .

The original Martin scale, summarized below, consists of 16 colors (from light blue to dark brown-black) that correspond to the different eye colors observed in nature due to the amount of melanin in the iris. The numbering is reversed in order to match the Martin–Schultz scale, which is still used in biological anthropology. In this case ...
"His right eye was light blue, while the left was black, nevertheless his eyes were most attractive", is the description of the historian John Malalas. [33] [34] [35] A more recent example is the German poet, playwright, novelist, scientist, statesman, theatre director, and critic, Johann Wolfgang Goethe. [36]
Moderate amounts of melanin make hazel, dark blue and green eyes. In eyes that contain both particles and melanin, melanin absorbs light. In the absence of melanin, the layer is translucent (i.e. the light passing through is randomly and diffusely scattered by the particles) and a noticeable portion of the light that enters this translucent ...
Red versus green; Blue versus yellow; Black versus white (this is achromatic and detects light–dark variation or luminance) [3] Responses to one color of an opponent channel are antagonistic to those to the other color, and signals output from a place on the retina can contain one or the other but not both, for each opponent pair.
Uranus is usually seen as a pale green or cyan. In fact, however, they are much more similar than we thought. Both planets are a particular shade of pale, greenish blue, according to new research.
