I have a few themes where the highlighted text is white.

Currently I'm using AlienwareBerry and Ipodberry both found on stack and created by ecruz0102 there is also Litho theme created by E3BK and the Pearl version has the white text when highlighted. Also the 81xx: iPhone Clone Theme by alexdemers has the highlighted text as white. All are OS 4.5 for the Pearl.

While I am not a theme designer, and don't "like" to be a critic when I can't do my own. It can be done, the question is how?
