148nm is on the lower end of UV-C. It's higher-energy than the furthest ultraviolet light that the sun produces (200nm). If it were produced artificially, it'd be heavily absorbed by the atmosphere to the point of near opacity. If the visible spectrum was an octave, where the "tone" of a color wrapped around from red back to blue the way G wraps to A, it'd be the blue one octave above visible blue.

Nice to hear the octave relation used!

"blue above visible blue" is a good name.. hmm, a little web tool to name these would be neat ;)

Out of curiosity I googled to see if there's formal names to things beyond UV and a SO question came up saying Klingon has a word for a color that falls within the UV spectrum, Amarklor; it "falls between violet amarklor (dark violet or purple) and amaklor-kalish (almost black)".

Else there's Octarine from the Discworld books, it's the colour of magic.

Another one in that same SO thread is err, quantifying synesthesia in the study of "chromophonics", where sound is assigned a color and vice-versa, that is, one could name a colour after a sound, which matches up with the earlier "octave" analogy.

Good name for a rock band. Or some tv series.

But better would be a prog-rock album named:

Supravisiblue

Indeed. In German, "blue" (blau) is sometimes used to say "drunk/inebriated" which makes the name all the more appropriate for a rock band, I think. :)

Surely it would be a blues band.

Teeny nit, the sun produces light well into the x-rays (mostly from the corona though). You're probably talking about sunlight making it through the atmosphere.

[whatshisface]

I'm talking about the blackbody radiation of the sun's surface, which accounts for almost all of the light. The X-ray flux at earth is 11 orders of magnitude lower than the blackbody-related flux.

It looks like "chromophonics" is a thing to link colors with tones (synesthesia)
