Automatic Light/Dark theming using HSLuv about lush.nvim

[rktjmp]

Not against adding more operators if they have a clear use and are ergonomic.

Could you post a bit of sample code for what you're talking about with invert and widen specifically?

Just off the top of my head:

• Immediately I wonder what the term and "short" name would be, which is kind of silly but it's part of "the feel" of lush. "invert" may be confused with "opposite", which is probably why you wrote "invertLightness".
• Also not sure if I want to add operators for only one color type or not (not sure how reliable the operations would be for HSL).

Forgot to post my side project
https://bitbucket.org/erlandsona/resourcery/src/7ec5cf57f783d872a936ea6afe28b97de6bdee81/lib/Colors.elm#lines-435

There's my implementation of "widen". invert should be in there too.

Weirdly enough what I wanted was to think about colors in hsl (as if I was using the additive colors I learned as a kid) but then I just use hsluv to ensure accessibility by "fudging the brightness" of each "top layer" color (non-greyscale) till it meets accessibility requirements.

You can do it in raw hsl but you have to write a loop/recursion/fold (which is weird to think about with colors) and it gets finicky around the boundary cases...
