:CGW I'm shocked! Surely you know that single-wavelengths are the curvy outer boundary while the inner curvy line shows the response to blackbody spectra. ;-) -Fred [[Special:Contributions/173.245.52.61|173.245.52.61]] 19:55, 6 January 2020 (UTC) | :CGW I'm shocked!

::Thanks for that; I was about to question the statement myself. All in all, I feel the current explanation of the chromaticity diagram doesn't really explain much, and seems unnecessarily biased to boot. I know just enough about chromaticity to think it's wrong but not enough to correct it.

@Fred - mea culpa. I should think before writing. Fortunately :-), the ratio of the colorspace to any 1-dimensional line's area is still infinite! [[User:Cellocgw|Cellocgw]] ([[User talk:Cellocgw|talk]]) 20:33, 6 January 2020 (UTC) .... now that someone did post some explanation of CIE, more comments. The current CIE spec may be paywalled, but it has changed little if at all over the last 40 or 50 years, so it's not all that hard to get the values. There are several sites (naturally I've lost the URLs) which provide algos to convert HSM to RGB to HSV and so on. See Wikipedia, https://law.resource.org/pub/us/cfr/ibr/003/cie.15.2004.tables.xls , and similar repositories [[User:Cellocgw|Cellocgw]] ([[User talk:Cellocgw|talk]]) 20:44, 6 January 2020 (UTC) | @Fred - mea culpa.
