I'm with @Vasil4y92... Bring back color and give us a BLACK background option! I've actually been turning on the Invert in the Mac Accessibility Control Panel, and as long as I'm working on design, not photos, it's very soothing.
Bluebeam, Pixelmator, and Adobe (dark Gray) really know what they are doing! Even Apple's creativity apps (Garageband, iMovie, Final Cut, Logic, and optionally Photos) use the dark gray, and color icons really POP.
Think it through... you can give certain color ranges a purpose, such as red representative of a warning, while green means something is active (we do still have this in Teamwork Reserved Indicators).
We're getting used to it, but there's still a lot of grumbling out here.
