:::I agree that explanation isn't great, if it's not improved when I have free time tonight I'll take a stab at it. Or maybe CelloCGW will, since he IS an optics guru (which is why I had to raz him).[[Special:Contributions/173.245.52.61|173.245.52.61]] 20:13, 6 January 2020 (UTC) | :::I agree that explanation isn't great, if it's not improved when I have free time tonight I'll take a stab at 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.

:I redid the CIE explanation - focusing on describing the diagram, rather than one thing it might get used for (e.g. black body). I think the diagrams on the right are labeled chaotic because they are not some neat geometric shape over-all. I didn't really follow much of what was there, so feel free to revive some of it if it seems useful. (My background in color theory comes from computer science and graphics, rather than from physics or hardware design.)
