Is the "amount" of net highlighting cofigurable?

Is there any known option to configure the amount or contrast if I highlight a net? I’d like to fine tune this to fit my color scheme since the darkening of the background is a bit too heavy for my taste.

Try Preferences → Schematic Editor → Colors. And Thickness can be adjusted in the Display Options.

Sorry, I forgot to mention that I mean the highlighting in PCBNew. I did not find anything regarding this in the preferences.
