When editing a color scheme (settings, Global Theme, Colors, then select a theme to edit), there are a gazzilion options when using “color set” roughly 10 in the pulldown menu and 10-20 under each pull down.
Is there documentation for what each of these does? It’s a bit of a pain to experiment with each to find what I want to set.
KDE Neon 6
Personally I don’t think ‘documentation’ can improve on the interface, which shows previews with tooltips. The biggest headache is just knowing how to name all of the elements, and understand the language involved. It is a complicated task and I really think cannot be simplified by creating documentation (there comes a point where the documentation would un-necessarily complicate the issue).
Important tips:
It’s a labour of love, but you should end up with a couple of good basic themes which suit your personal situation/tastes/monitor/eyesight etc.
Anyway - just to help along, I’ve an archived bundle you could grab and mess about with.
Remember, these are text files. You can open them in your editor, find out where the name goes (here - I’ll copy one, and name it ‘TESTER’) then edit a colour in the GUI, save it, and then view the difference in your text editor (I use Kate).
So here you’ll learn the language - in the text file, the numbers are RGB (116, 108, 134) for the paler purple - the old value was 69 , 40, 134. Also the name in GUI was ‘visited text’, listed in the file under several views… ‘ForegroundVisited’ under [Colors: and then subsections Window, View, Tooltip etc.
It’s a faff. When you get your contrast/brightness sorted, then you can go in and simply adjust the ‘Hue’ to get variations on a theme.
Marble is a good one, as is ‘Card’ (cream/green) and for dark, I tend to start with a completely desaturated theme - all grey, zero saturation. Once that’s right, you can clone it and choose a hue, and play with saturation.
Thanks for the link to the archive!
The preview works “ok”. But to a novice KDE user, the nomenclature is unclear. I have to know what:
“View, Window, Button, Selection, Tooltip, Complimentary, and Header”
all mean, because the preview for all those is the same; boxes with text.
Lolz I’m not a novice, and the ‘nomenclature’ is heavy… it’s a labour of love, and it’ll take time to get colour schemes that are just right… find something that doesn’t work in your spreadsheet, then you have to go back and create another option…
I test mostly in Dolphin, save the scheme, kill and restart dolphin - it’s mostly hit 'n miss.
The downside of being extremely configurable.
