Does anybody have HSV or other values for white light of different color temperatures?

Does anybody have HSV or other values for white light of different color temperatures? warm white, cool white, daylight, etc? I know there’s a color temperature operation but I’m looking to change individual LEDs without making a global change.

Also, perhaps there should be some CRGB default values for things like: WarmWhite, CoolWhite, DaylightWhite?

Did you start of here:

I’m thinking I could use RGB values and just drop the blue value lower to make the color temperature warmer? But are there any standard defaults that line up with certain common lightbulb hues?

^^^ ooh nice, I knew that stuff was somewhere… I’ve been having a hard time navigating through the documentation to find where the references are…

Am I correct in assuming the following three numbers are RGB?
Candle=0xFF9329 /* 1900 K, 255, 147, 41 */,

Yes, 255 147 41 are RGB values. Have a look at the first table on this page for some other Kelvin values as RGB.

This is good too, allowing real time scrubbing through temp range.
