Red and violet are the far ends of the spectrum and both have invisible wavelengths named after each other

Green is the most visually prominent and represents the center of wavelengths

Blue, cyan and yellow are all primaries

Magenta is the sort of imaginary bridge between red and violet

As far as I know orange has no justification to be with the big leagues of colors. Everyone always dogs on indigo for only being present for the nice seven but orange gets a free pass.

Are there any colors that are big in other cultures/languages but not in the west? I know some languages don't distinguish between blue and green or might lack something like orange

If it works better with ten that's fine too
