Change your Mac displays contrast
Something I never really paid much attention to was the software side of my displays contrast, something that you can change by using simple keyboard shortcuts:
Decrease display contrast: Command+Option+Control+,
Increase display contrast: Command+Option+Control+.
The default is set to the lowest level of contrast, and increases will generally wash out screen colors. The ability to change your displays contrast is actually part of the Universal Access utility in Mac OS X and is intended to aid those who are visually impaired in seeing things on the screen.
The screenshot below shows the Chrome browser looking at OS X Daily on the highest contrast:
