Visual accessibility concern

It is hard to see on TUI with a background like `make menuconfig` `nmtui` `yast`.
fyi: tried frappé and mocha.

Reproduce the visibility problem using Kitty with backgrounds from make menuconfig, nmtui, and yast, comparing the frappé and mocha themes mentioned in the report. Inspect the theme definitions and verify that the affected text and interface elements remain readable across those backgrounds; done means the contrast concern is resolved and can be demonstrated in each reported context.
