This is true, and illusionary at the same time.

While our precise perception of red may not match, the interplay between colors is such that people perceived them to go together, or clash, etc, in a somewhat consistent fashion.

This means that, over the general population the perception of color is very similar from person to person. Ignoring genetic defects.

I worked in a creative shop, so we sold a lot of colors of ink, paint, crayons etc.

It’s interesting to watch people trying to pick “red” when there is like a whole gamut of red. Not only that, but it depends on the lighting around as well. (Is it evening, day, what kind of lighting fixtures are there?)

Creatives usually have 10 kelvin white boxes for a neutral color experience. A bit like audio folks have calibrated monitor speakers.
