Description Marcos Dione 2023-10-16 09:02:09 UTC

Several parts of the KDE ecosystem have the concept of color themes: Kate's syntax highlighting, application colors, etc. And yet, when trying to pick a color with the color Dialog, the colors of those themes (their palettes) are not easily available. Even more, when the dialog is modal, the rest of the screen is darkened, which renders the pick color tool useless.

Hi Nate, thanks for looking into this, but in fact, my request was more in the lines of being able to feed the color dialog a palette from which to chose colors. Should I open another bug for that?

Comment 3 Nate Graham 2023-10-20 13:19:54 UTC

Sure, though that's something totally different from the issue here, and I suspect not very not feasible, IMO.

It would in all practicality require KDE to override the default Qt color picker dialog with our own, and then implement this feature in it--whatever that feature would look like.

AFAIK, KDE already does that with other dialogs, like the file open one.

Right, it's possible, it's just a lot of work since someone would need to write an all-new color picker dialog for KDE, and it would need to be measurably better than the default Qt one to make it worth the effort.

Looks like both "Dim Parent" and "Dim Inactive" should be disabled temporarily during color-picking. Maybe "Screen Edge" too.
