I'm not sure which pxm# resource contains the the left and right sides of the Listbox header. To illustrate what i'm talking about I have a normal picture with a listbox header:

and then a zoomed in picture of the left side of the header:

I want to replace the grayish colored pixels blue ones obviously to match the rest of my theme. Any theming gurus know which pxm# I need to edit?
