Your analysis of human sight is very insightful. I wonder if there is any truth to the claim that woman can see more colors than men on average... or if there are any people born with an enhanced ability to see more of the light spectrum than the average human. Thanks for the great read and good source references too!

Not enhanced abilities per say but there is a slight difference in each individual, for instance few years ago a Dress pic dominated social media, the color of the dress was seen differently in two groups of person.One group see white and gold, while the other group see black and blue,.

I really don't know for sure, if you find something let me know ! Anyway thanks for stopping by ;)(
I personally see black and blue colors ! Anyway to respond to your other question
I think it's because the genes for the colour receptors are on the X chromosome. XX woman have two chances to get the genes, XY men only have one!
That's partially true, the two main genes for color vision are OPN1LW and OPN1MW.They are found on chromosome X and one can have more than one copy for the OPN1MW, but why i still ignore that ! Maybe two copies makes the activation of these genes more intense in women, i really don't know
