Fonts and graphics are slightly “fuzzy”. Colors are not correctly displaying

After Mavericks installation on my Macbook Pro mid-2012 (non-retina), the fonts appear slightly fuzzy, the graphics seems less crisp and the colors are just "off". This issue seems to be system wide but is much worse whilst using Safari for some reason. (Safari 7.0)

Please advise and thanks in advance for any and all help/suggestions!
