How to keep a color scheme of "Pluma" whatever desktop theme I may choose

I use Pluma as my favorite text editor. I prefer it to Gedit, for exemple.

I customize Pluma especially concerning its color scheme. I like the "Kate" one.

The other days I found this :
On Jammy, whenever I change the desktop theme, the color scheme of Pluma goes back to "Yaru" scheme instead of Kate one I chose beforehand.
I don't like Yaru one so much. So this going back to Yaru scheme annoys me.

Does someone tell me how to stay with, for example, Kate scheme of Pluma even when I change desktop themes ?
