Change Editor Colors?

[Chadi]

I'm looking to change the background / border color of the editor (any, standard or wysiwyg versions). I was not able to find where to do this. I've searched the template by a simple color code such as:

B7BCE2

No results. I've used FF web developer extension to trace where the CSS is coming from, only the outer border is found in the vbulletin_editor css file under clientscript directory.

I checked Main CSS area under styles options and found nothing regarding this still.

Any help on this appreciated.
