No, but they could use some safety goggles on windy days.

That description is just as good as the one in "Changeling" (the novel about Peter "Professor" Clarris) with its reddish description. From a biological standpoint the most likely natural mechanic would involve electrochemical reaction based on near-infrared (similar to the electrochemical reaction for normal light, just with a different base molecule) and one's brain could turn that into grayscales just as well as varying degrees of red or even more (for us unpronouncable) colors. At least you didn't opt for the blurry rainbow colored variant usually associated with long wave infrared in classic thermographics.

They aren't unpronouncable, they just don't have names. If we could see those wavelengths, they'd have names.
(Personally I'd go with Octorange)

~clap~ So you had to nitpick ...



... but the point is, that we simply cannot see them. And just like a person, who has been blind since birth can ofc technically pronounce a color name as long as he/she isn't simultaniously mute, he/she simply won't be able to pronounce in a meaningful way, where both the sender and the recipient have an identical concept associated with the word. Thus my use of the word of unpronoucable. I'm sorry if that comes as an insult to your understanding of the english language.



Personally I'd use normal colornames with an added syllable: hyper-red, hyper-green, etc. with hyper-white being the mixed color of all sub colors

Aww, you missed the reference.
Well never mind, I screwed it up anyway.
