> Your previous comment had stated that hues are electromagnetic frequency and parent comment showed a counterexample

That was not the point, and said counterexample is not such (also magenta is, in a way, "electromagnetic frequenc[ies]"). Impossible colours - virtual colours - do go more towards the counterexample, though up to a certain point as they refer to the mental phenomenon of colour and leave the physical nature of colour untouched.

But finally I get what you meant when you stated: «not all colors are electromagnetic frequencies». True ("not all perception is produced by a direct influx of"). But also false, apparently (to the best of my), as objectivized hybrid colours are compositions of electromagnetic ranges; objectivized virtual colours are as well etc.

> Color is a complex phenomenon that cannot be reduced to electromagnetic frequencies and their composition

Yes, and nobody ever stated the opposite - no reduction was never implied, no «overlapping» (as written in the other post): the point was expressed, nearby, at https://news.ycombinator.com/item?id=31217999
