I am looking for a theme I have seen in a video from the KDE Community Youtube channel, this video at 1:16:
https://youtu.be/HdirtBXW8bI?si=qpi3twMbU5i20Vu-&t=76
Screenshot of this theme:
The taskbar, the colors and the icons are just awesome!
Where to find it?
Thank you @dzon for your help!
This is all I could do with Carboniferous and others appearance extensions.
Well, things are done the regular way. The colorscheme goes in ~/.local/color-schemes. The gtk theme goes in ~/.themes and the konsole part in ~/.local/share/konsole. For the icons youâll need one that adapts to the color scheme ( breeze, breeze chameleon RC etcâŚsome). If you want the wondow decoration to match youâll need something like breeze, lightly,klassy etcâŚYou canât use some fixed aurorae theme. Same goes for your plasma theme. Youâll need one that adapts to the color-scheme OR one that doesnât contain itâs own color settings. Youâd need to check the theme in ~/.local/share/plasma/desktoptheme/. As for the browser, firefox pretty much doesnât give a râŚ'S a⌠about gtk, so youâd need to find either that theme for firefox OR install the firefox color addon OR fiddle with the userChrome.css. Since you use chromium (-based) ones, youâd need to set them to use qt instead of gtk for the best match. That is, unless the gtk has a specific chromium line or two.
Like so:
As for the gtk apps, you can either set them to use Carniferous as default OR launch application specific using the Exec=env GTK_THEME=Carboniferous-Gold whatever
Like so ( example: Catfish):
Thank you @dzon for your explanations. Everything seems clearer now.
You have to choose icons or window decorations that fit the color scheme.
For the window decoration I selected Lighty and unchecked the Lightly option âDraw titlebar background gradientâ. I could also edit the Carboniferous-gold color scheme.
But I could not find a plasma theme that adapts to the color scheme, the font colors are good but not the taskbar background color. There is no category like âAdapts to the color schemeâ in the KDE Store|Plasma Themes
https://store.kde.org/browse?cat=104&ord=latest
And the icons color are black in LibreOffice or in the Global Menu, which is not adapted to the general view background color but I couldnât find any solution to get them gold by editing the colors scheme.
I got pretty close to the original screenshot, though. 
MyeahâŚthat store is a mess. But umâŚBreeze no panel shadow, Utterly round, PeaceâŚetc are plasma themes that adapt. In either case, you could always edit one that adapts and make more changes to the svgâs in the theme with Inkscape. Youâll find that stuff in ~/.local/share/plasma/desktoptheme/theme/widgets/ (panel background) and ~/.local/share/plasma/desktoptheme/theme/dialogs/ ( menu).
Try this one, for example. Adapts with no transparency in the panel. Very simple theme.https://store.kde.org/p/1178558/
Thatâs crazy all we can do by default with Plasma.
I could change also the default icons of my taskbar apps just by right clicking on the app and then âEdit applicationâ and change the icon.
Unfortunately this does not work for flatpak apps, I get the error:
Could not save properties due to insufficient write access to:
â/home/adamy/.local/share/applications/net.cozic.joplin_desktop.desktopâ.
So I get one blue icon not with the color scheme dominant color.
I also tried to modify the Brave svg icon with Inkscape, but unfortunately itâs not with dominant color scheme but with grey light color, whereas the icons is a little bit transparent.
Is there any forum where we can find help to create an icon with plasma color scheme?
How to deal with the write access issue of flatpak apps to change the icon? Unfortunately, Joplin has no deb package and I use it every day.
Thanks!
Did you mean something along this
Exactly the doc I needed, thank you @artytux!
Found he icons step at this page:
https://develop.kde.org/docs/plasma/theme/theme-colors/
Quite strange, I didnât find this doc by a google search with keywords âkde plasma icons with user accent colorâ, there is no results to the subdomain https://develop.kde.org
Is it well referenced by Google?
I could find icons for Brave, Chrome, Chromium, Thunderbird, Emacs, Gimp, Inkscape, Joplin and Kate with the same style and change the accent color:
I just did a copy paste of what found on the doc and itâs done!
I donât understand why Dolphin do not apply the accent color and it looks dark because I think it applies the css color
.ColorScheme-Highlight
{
color:#232629;
}
Is it normal? Anything to do on my part to make the accent color work in Dolphin as well?
To create a full Global Theme all icons should adapted to accent colors but I feel like there is hundred!
Close to perfect!
Not sure why you want the icons in the icon folder. Anywho, I think you couldâve saved some time by running the icons through gimp or inkscape and use those for the applications ( edit applications>icons).
Not long month or two after DuckDuckGo arrived on the radar I stopped using Google and have used DDG since, not bad for Linux searches takes it a while to get used to your searches sometimes you have to gently steer DDG in the area of the search in small steps, but it does OK,
Typed in = create an icon with plasma color scheme at DuckDuckGo
Result is = create an icon with plasma color scheme at DuckDuckGo
Are you familiar with the top menu > file > print > use the destination > save to PDF ,
TIP change the name to a name to easy search (EG = Icons -themes ) tack that on at the start of saving pdf
Hope it helps.
@dzon Idea is 
Thanks dzon.
