Dorico 3 - any way to change the color of the blue background?

Screenshot attached to show what I mean. That blue is just really annoying at night… Any way to change its color? And what about the paper’s apperance? (to make it look less white and more yellowish)

No.

In the Preferences > General > Window section you can choose the Dark or Light theme and that’s it.

It may not be what you want…but I use f.lux to make everything yellower.

I’ve switched to the light theme just to make the blue tolerable.

It’s a very pretty blue, nicely chosen, but … visually taxing when I’m trying to work on the score. The background shouldn’t be more prominent than the content!
