I need more free time :$
then I'll try to compose graphic charters -I've been toying with/around a single color (#ace12d) for years.
You could toy with/take inspiration from (reddit) r/unixporn if you're interested in graphic charters: most members have their color schemes posted on github > https://github.com/topics/unixporn.

I may not be the best adviser for color schemes but, well..
Maybe true, if the skill buttons keep their original colours - it's a kind of 'all or nothing' situation.
I may be biased tho ^^ I may like it better because I've seen this blue frames and buttons everywhere for 30+ years, especially in the Microsoft kingdom... overdose!
A trick I've been using is choosing a coloured grey for bg, frames & tables. As an example you could swap #413934 for #222528 (a very dark blueish grey), toying with differences, here +3: R 22+3=>G 25+3=>B 28. If you want a oranged grey, just switch B value (22) with R's (28) => #282522. To obtain a lighter blueish grey, just augment the first digit of R, G & B: #273033 or #323538.
In this case, you could try to customize the frames by selecting a darker variant of the topbar button colour #6E5359 and darken it.
Edit: 20 years ago, I was sometime using Color Schemer
just found this fun, free and safe online tool with a good ergonomy/usability IMO: https://paletton.com
