XF 1.2 Visitor tab help

[iGloo']

This is a simply question, I would like to be able to change the color of the selected (text and background) as the screenshot show: http://prntscr.com/2yar1n because the red color do not look good with my style...
In fact, i'm just looking WHERE to go to change exactly those things.
Thanks in advance.
