Oh cool, I'll give it a go and see how things look! Thanks for making this!

@Akselmo , I just deployed @themerdev/kde-plasma-colors to npm and added it to the web UI as well.

I installed Kubuntu in a VM to test, but I don't use KDE full-time so feel free to take a look and let me know if I screwed up any of the color mappings. PRs welcome for any improvements there. 👍

I'm not sure if I should create separate issue for this but anyway, here's my feedback after quick testing:

Works pretty well out of the box, I did some changes to the scheme, mostly switching the colors around since I wanted blue instead of yellow for selection. I do change colors around a lot in other themes too so that's not really related to Themer though.

Anyway, one thing I noticed that accent7 wasn't really used anywhere, at least in color scheme settings. In color set "selection," link and selection colors were pretty much the same. I would change accent7 to the link color perhaps. Alternatively, making accent7 the selection color could also work.

Other than that I have no complaints :D Made it really easy to get similar color scheme all around my system and I'm happy for that.
