Is there any good reason getRGBA() should take out parameters? Is it just for ADL to distinguish between float and double? Is the double version really necessary or used (I ask without looking)?

I will try this a follow up cleanup.

I think you want to forward declare FloatComponents in this file.

No, getRGBA, getHSL etc can return FloatComponents. I'll do that in a followup.

Ok. Cool. Can we reconsider the name FloatComponents. I would much prefer something that included the work Color in it. Perhaps just ColorFloatComponents? Or make it a template and combine it with ColorComponents to create ColorComponents<float>/ColorComponents<uint8_t>?

Or add some additional types and have RGBAFloatComponents/HSLAFloatComponents/HSVAFloatComponents?

Excited to see this progress. I have notes about a lot of improvements for Color that I’d like to make, and I hope after you do some of these things there’s almost nothing left for me.
