Theme option for changing backface color

In older versions of blender, backfaces appeared blueish. Apparently this was a bug so it was removed. It was so useful though! You knew the face orientation the whole time you were modelling. Now you have to go through the viewport menu to switch on the 'face orientation' mode, which is so saturated that it's impossible to model with, you have to switch it back off.

Please add an option for changing the color of backfaces from the theme. This is seriously annoying. Or alternatively make the existing backface viewmode WAY more subtle so it can be kept always on.
