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.
- pmayrgundter 3y agoNice 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 ;)

- beretguy 3y ago> "blue above visible blue" Good name for a rock band. Or some tv series.
- NateEag 3y agoBut better would be a prog-rock album named: Supravisiblue
- adrianmonk 3y agoSurely it would be a blues band.

- codethief 3y agoIndeed. 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. :)
- Cthulhu_ 3y agoOut 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.
- Cthulhu_ 3y agoIt looks like "chromophonics" is a thing to link colors with tones (synesthesia)
- ngoldbaum 3y agoTeeny 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 3y agoI'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.
