Noobslab theme tiny glitch?

view story

http://askubuntu.com – I have a dark theme on 12.10 I really like that has 1 issue. Every dark theme I've tried with unity and GTK has been showing light shaded characters on google or any other white colored search bar or engine. I learned there is a way to correct this with dark themes. What are the methods for doing that type of task? (HowTos)
