Hardcoded colors clash with dark mode

[nicrie]

Version 2.10.1 now seamlessly integrates with my internal dark color scheme, offering a visually pleasing experience. However, there are a few instances where hardcoded (?) colors clash with the overall aesthetic:

• The currently activated field appears to retain hardcoded colors, as illustrated in the image below (depicting the initial state upon startup). When clicking on Show answer, the rating buttons 1-5 adopt the correct background color, but Show answer itself has a bright background, resulting in low text contrast.
• Tooltips displayed upon hovering over elements (such as icons in the top bar) exhibit a bright background and text combination, offering insufficient contrast (not visible in the provided screenshot).
