It’s more complicated than that. The eye has multiple genes for multiple pigments. There’s eumelanin (brown) and pheomelanin (yellow), plus the back of the eye reflects as a blue color so the lack of either melanin means blue. There’s no green pigment, instead, the blue of the eye plus the yellow of pheomelanin makes green, with no brown pigment meaning quite green, but some brown pigment means more hazel. Different combinations make different colors than those I’ve mentioned.
