I think, I screwed up the color profiles on my macbook
This is probably caused by bad color calibration profile. You could load the default profile for your hardware, or try to calibrate your monitor.

Try loading the default profile of your display. This is done by opening Preferences -> Displays, Choose the Color tab and select the Color LCD (I'm asuming MacBook PRO, on other machine or external monitor this will be different).

If this doesn't help - try calibrating your monitor by pressing the Calibrate.. button and following the onscreen instructions..
