Field Colors: Use White foreground color when dark background is selected

If I select a dark color for a field, the field text color is still black, so it can be difficult/impossible to read.

Please automatically change a field’s text color to white when the luminance value the background color is < 0.5 (or whatever the appropriate value is).

Update: This only happens in certain circumstances, like when the color of a Single-Select entity is edited later.

Added to the backlog, will discuss with designers and developers :face_with_monocle:
