The background color in fields defaults to 0.15 opacity. While this improves readability, it reduces the choice users have. When it comes to accessibility and recognition of colors, it would help to the option to choose darker vs lighter colors. I know this means the text color needs to change dynamically as well then, and it might make for more ugly workspaces. So maybe it could default to 0.15 opacity, with an option to make adjustment (when holding option key?)
I don’t know how realistic this is, but it was a blocking feature someone needed that prevented them from using fibery, so I thought I’d put it on here.
