Description (*)

The openmage design contains way to many colors, with many being used only once, or just barely different.
It also contains multiple definitions, which are not used anywhere or are doubled.

Questions or comments

Currently a draft, as I'm not sure what to use to compile the scss without it containing unrelated changes.
I'm currently using sass 1.97.3

initially this was supposed to be an upgrade to add focus colors and such, but with this many colors it needs to be streamlined first. :(
(and selectors reduced, the amount of useless overrides makes it really hard to find the correct selector to update)

new datepicker with openmage blue:

new user menu, like the normal navigation:

@sreichel do you have an older sass version to compile the css files without unrelated changes?
Otherwise I can compile then but functions like darken would be translated to something like rgb(230.35, 230.35, 230.35) and some changes to how numbers are written.

Buttons now have a consistent hover/focus effect, and get darker not lighter.
I didn't rename the grayscale colors (or removed all color functions) for now, only condensed them .

I broke my pc, cant check atm. Ive used compass from https://docs.openmage.org/developers/tools/ddev/#installing-compass

I used the newer version and removed some changes by hand. the replacement of some hex color codes with rgb seems to be on purpose by sass, as converting them back would lose precision. (not really needed for us, but whatever)

The PR is ready to be reviewed.
