I really like Resharper's marker bar, but I have a form of partial color blindness (deuteranopia), and I'd like to make the green and yellow status indicators more distinguishable. Obviously it's not a big deal since I can inspect the bar for yellow ticks, but if changing it is possible it'd be a nice touch.
Resharper 7's status bar is much more colorblind friendly, since it uses icons instead of just changing the color of the square.
