Isn't it in the Control Panel text section?
Apparently not but it could possibly be one of those things win7 has proprietary control over because I noticed your font color in the example is green where mine on a blind I'm working on is dark red (maroon). The text colors I'm using on the blind in the Control Panel text section are dark brown, gold (kinda) and tan. I don't see the shades equaling dark red after some weird Win blending but who knows?
