Surprised to see the list of common color distinctions used by 'most' languages, included 'orange'.

In many languages that word 'orange' only appeared once the fruit appeared as a trade item. Like 'salmon' or 'ivory', it's a color-word that borrows from something that is that color.

Previously in English for instance, orange was just a shade of red. Why we say, 'red robin' and 'redhead' though those things are more orange; they were named before 'orange' was a color.

Possibly why 'fire engine red' has that qualification? That's simply 'red'. Because fire engines are not orange? So 'red' was insufficient to distinguish from orange, and had to be qualified. Just a guess.
