Basic primary colour perception varies by sex.

Basic. Red. Yellow. Blue. Rainbow colours. Not terracotta versus rust. [former is red-orange, latter more brown]
Primary colours too. So this would really throw the cat among the pigeons for any upper level function since a man and a woman can look at literally the same object, same section of the nm spectrum and still disagree/misperceive.

Not that it supports the “nothing is objective” philosophy. These things are quantifiable with optics. The difference is labelling and perception between sexes based on what their senses are capable of perceiving. Cat, pigeons.

That might not be male simplicity or stupidity, as is often claimed, but a difference in colour processing in the brain. Women, being gatherers in tribal societies, required higher colour discrimination than men, who often only needed to catch what they were chasing. Lo and behold;

Guys’ eyes are more sensitive to small details and moving objects, while women are more perceptive to color changes, according to a new vision study that suggests men and women actually do see things differently.

Abramov explained in a statement these elements of vision are linked to specific sets of thalamic neurons in the brain’s primary visual cortex. The development of these neurons is controlled by male sex hormones called androgens when the embryo is developing into a fetus. [and according to pro-choice feminists, not really a person]

“We suggest that, since these neurons are guided by the cortex during embryogenesis, that testosterone plays a major role, somehow leading to different connectivity between males and females,” Abramov said. “The evolutionary driving force between these differences is less clear.” [he says tongue firmly in cheek]

Vive la Evolution!
