Ever wanted to have light and dark apps live side-by-side in harmony, well now you can. With Gray, you can pick which apps should use the light and dark appearance with a click of a button.
You set your Mac to use the dark appearance, then use Gray (a frontend for
defaults write) to configure individual apps to use the light aqua appearance. I only left dark mode on for a half hour or so, so this app isn't for me. I'd love to see screenshots of this in use, though. Maybe I'll be converted to the gray side.
