separate color style

Is it possible to start one application in another color style
instead of changing everything.

I want to startup only kdenlive in a dark for example Obsidian Coast or Wonton Soup color style.

All the other applications “oxygen style” .

No.AFAIK (to satisfy the minimum length rule for replies).

No. Only apps that come with their own theme capacities have this. Maybe some hacking of config files can be done.
