Depending on what kind of monitor or screen you are using, you may have to calibrate your display to get the proper color settings. Calibrating is highly recommended even if you think everything looks wonderful.
You can calibrate your display in Windows 7 using the Display Color Calibration wizard. You can get to this by going to Control Panel, clicking on Appearance and Personalization and then clicking on the Display header. Then click Calibrate color in the left menu.
I hope this helps!
