I always learned “ROYGBIV” as the colors of the rainbow. Red, orange, yellow, blue, indigo, violet.

What’s up with the last two? Isn’t indigo basically just dark blue? Why is it violet and not purple? Can’t it just be “ROYGBP”?

    There’s a similar lack of distinction between Green/Blue in the ancient world.

    How would that arise? There’s blues in the sky that are very distinct from the greens of plants. Or are the blue detecting rods (or is it the cones that detect colour?) that new that we can perceive blue more than they could in early recorded history?

      You know how some people can tell you the exact shade of two colors that you consider identical? Turns out that giving colors distinct names in our mind makes us way better at seeing the difference and that is how we chop up the color spectrum from an infinite number of colors to seven. You think blue is completely different because you went to school and being able to tell the difference between blue and green was a requirement for you. If the school told you that the sky is a light shade of green and the forest is a dark shade of green you would adjust your brain accordingly.

      I guess my point is that all colors are made up by the state and we indoctrinate our children into the government sanctioned system at an early age.

      They were simply considered shades of the same colour, that’s all. The light spectrum is continuous our breakdown of the continuity into discrete colours is purely arbitrary.

      The colour we call sky-blue is considered a separate colour altogether in Japan (Misu)

      Pink is named after the flowers Pinks and is called Rose in some languages but we use Rose for a different colour which is more magenta.

      Notice how we don’t have words for some colours so use adjectives (bluey -green) There are some languages that don’t use or have any words for colours but alsways describe them. For example “bright fire like”

      You can actually see it in modern times. The Himba tribe in Africa doesn’t have a concept of the colour blue. There’s not even a word for it, as far as they’re concerned blue is just a shade of green. To us it seems obvious, the sky is blue and the plants are green but to them it’s all different shades of green. It’s not a genetic thing, they’re seeing the exact same colours as anybody else, their culture just doesn’t distinguish between the two colours.
