1: You have a visual color impairness, sucks for you sorry dude.
2: Your monitor is old and it's colors are fading out.
3: Your monitors color and brightness setting are not properly setted.
4: None of the above!!
No really, but since I don't want to go into the folders and mess with files and probably screw something up, I'll obviously put up with it since it is such a miniscule pet-peeve (as I made clear).
And yes, I probably shouldn't have said both were yellow, cuz they aren't. The bar is yellow and the pic behind is a dirty yellow/orange...but obviously they are not the best contrast of colors.
