How did you get such a dark blue as the default blue colour
Anyway if you'd read the skinning documentation or looked at any other skin you'd soon see how to change the top parts of the contact list and chat windows.
from memory...
Contact list is

640.png
636.png <- might be something else.....
Chat window top bar

I too suggest you change them to blend in more with your default skin colours
BY THE WAY!
You god-damn better not be skinning on top of a patched messenger, it looks like you've used mess patch.
