Colors - Mixer

This is coming from a non-cubase user - my wife (she doesn’t use any daw)

But she was watching me teach my daughter Cubase and when I brought up the mixer she mentioned - the mixer is the same color background as the track work area and blends so well it looks confusing.

Suggestion: Allow the option of making the mixer a bit lighter than the work area so the two can be distinguished a bit more.
