You can see blue, because you have a word for it

The particular quality most english-speakers call color, is in the light. If a person or a population can't see a *color, it's cuz they have a visual or neurological deficiency, hence no knowledge of that color (and no native name).

This...

This all suggests that, until they had a word from it, it's likely that our ancestors didn't actually see blue.

...is horseshit.

We don't create Reality (and the things in Reality) in signifying; we categorize, distinguish, apply meanings to, Reality (and the things in Reality) in signifying, and we do this for ourselves, not cuz Reality requires it.

*or a shade of a color

Mankind changed significantly when his diet improved. For example, by eating meat and cooking food, then the humanoid brain increased significantly. Retinoid is another dietary contributor to vision. As retinoid increased in diets, then cones shifted from detecting mostly red (low frequency light) to also detecting higher frequencies (blues).

Retinal is also more commonly made available as Vitamin A. That theory is more based in science and not in vague speculations.
