White text on *custom* background.

Note:
+ You can choose your own favorite text color (a) as well as background hightlight color (b). Visit http://colorpicker.com to choose your (a) & (b).
+ Now, you have your two-fav right? Now go to next step :) If you haven't, I won't blame you for being still prefer the dafault hot-sexy-pinky :)
+ Simply apply these color by openning Stylish app in:
> Chrome: Click the Wrench icon -> Tools -> Extensions -> *Choose* Options -> Edit "Text hightlight" -> Now you can apply (b) in the "background" attribute, or (and) (a) in the "color". [You have to do this x2 time]
> Firefox: Open Extensions -> Stylish -> Edit -> * do the same as above code.*
When you're done, remember to Save.

Eg code:
::-moz-selection { background: #fc3; color: #222; text-shadow: none; }
::selection { background: #fc3; color: #222; text-shadow: none; }

Have fun! :)
