I use KDE Plasma, and much prefer the KDE color picker over the GTK one that Firefox uses, with input type=color.
I know that I can set GTK_USE_PORTAL=1 to make Firefox use the native file picker, is there a way to make it use the native color picker as well?
I know there probably isn't a way, but I figured it's worth a shot asking.
Excuse me for not answering the question but are you using the color picker in Firefox really that frequently?
I would just choose a nice color with the picker of my choice and paste the hex-code / type the RGB in the custom panel of the default FF color picker and that's it.
Not really. I just like tinkering, and customising things, and I wanted to see if I could.
Ah, I see! In that case I can completely understand your intention.
Edit:
I feel like the guy on Stack Overflow who says something like "That's bad practice, why would you do that?" and then the thread is closed.
And people who google how to solve a certain problem and get to the SO page never get to know the answer that would be relevant.
I'm not a dev, but I'm wondering if the 'Plasma Browser Integration' package has any influence on the picker? Or maybe there are GTK app settings in play.
Just a thought.
It really annoys me that Firefox is not more integrated in KDE than it is.
I have the plasma browser integration. It adds an item to “Share” in the context menu (for use with KDEconnect etc) and integrates Firefox with the media player.
Media integration should be done via mpris which ff does natively now, so that's no longer done by the plasma addon
