court:How to change advertisement boarder color?

Guys,anyone knows how to change the color of these advertisement boarders.I mean, I can't find where the file is located.I guess it should be somewhere in ****std.fsh.Here's the pic to show you what I mean"

You see, It's grey,and I want to cahge the color.Could you please tell me how to do it?
Thank you!

In the file xxxxstd_vram there is an image for otbl. That is the file you are supposed to edit.
To edit the sides you change the part on the far right.



Thanks for reminding me to update that a little bit in my patch
