Where can I change the selection color of objects from attached files ? (worksession)

Defaut is bright yellow for objects in the active file, but worn out greyish yellow for objects in attached file.
That’s fine by me, but I need to make screen captures to highlight all these objects without differenciation.
I checked in the color settings, and in “advanced” settings (what a mess in there !), but could not find a way to change this.

Does it exist ?

Hello - as far as I know there is no provision of this - attached files always use a killed version of the selection color.


OK, thanks
