How to make the color contrast in the Dorico 5 piano rolling shutter window clear and visible

I am a music enthusiast from China who does not understand English. I translated it into English using Google Translate. May I ask everyone: How to make the color contrast in the piano rolling shutter window clear and visible in Dorico 5? Where is the color contrast darkening set? Thank you first!

Hi, zjqh2o, and welcome to the forum.

The “piano roll” display in the lower zone (known as the “key editor” in Dorico) does not have any color options yet. It displays with the same colors in both dark and light modes.

Thank you!
