[Feature request] Allow option to edit text highlight color

[dreadbalaur]

Describe the feature

The text highlight color is set to be more saturated/deeper than the accent color in most other UI elements. I personally prefer the inverse, where it is a lighter/paler shade compared to the rest of the theme. Can we have an option to modify this in the css?
