Various devices use various backgrounds for their options menu. The problem this causes me is that the gray-ish icons I use for my options menu buttons don't look great on darker menu backgrounds. From my reading and experimentation I see three options for dealing with this. Number 3 is the one I intend to do, but I have a question about implementing it. Also, I would be very interested in any general thoughts/advice about this issue:
Use icons that look good regardless of the background color. Maybe dark-ish gray icons with white-ish outlines? This would be an easy option to implement, but getting the ideal icon is tricky.
Set a custom background color. The code for doing this appears to be very hacky, and this results in an options menu that doesn't conform to the device theme.
Have 2 sets of icons, programmatically set one light-ish menus and one for dark-ish menus. This seems promising aesthetically, but I can't find how to determine the color/lightness of the background?
