Most cultures agree and recognize the existence basic colors: red, orange, yellow, green, blue, purple. This is demonstrated by the existence of equivalent words in the languages of these cultures.

However, cultures don't agree on where the dividing line between these colors is. So if you had a spectrum printed out on a strip of paper, and you asked people around the world where green ends and blue begins, you would find a variety of different color boundaries.

This is often cited in discussions about whether language changes how we see the world or whether language is a reflection of the world we see.

Some cultures, usually considered primitive, do not recognize or distinguish as many colors as English speakers and many other cultures. Russians actually have one additional color - what we would call dark blue and light blue they consider two distinct colors as different as red and orange.

If I am remembering correctly, there was a native group in the USA that didn't make a distinction between yellow and orange, so if you held up color chips and asked them to identify the different colors, they would screw up in distinguishing between these two colors. More interestingly, as they learned English, they became more proficient at distinguishing the two colors, and this proficiency correlated with their English language ability.

Sometimes things that we might assume to be universally true are only true within our own context.

How is right and wrong (truth) determined?

It seems there are only three options for determining truth:

Truth is determined by a transcendent source (e.g. laws of math for mathematical truth, divine for spiritual/moral truth.

Truth is determined by a small group of elites (e.g. the vaxx is safe and effective, mostly peaceful protests)

We each determine what is true for ourselves (which is actually a false choice - just try this in the face of those pushing option #2.

Much of the fight today is actually not about whether the grass is green or blue. That is largely irrelevant. The real fight is about the ultimate source for truth.
