Background BB Code and PM Background Help

[stilly]

Cant figure out why I cant change the BBcode_code back ground and PM input background.

It is white and text is white, want to change the backgrounds to #121212, I have looked through stylevars cant seem to place it, or at least any changes I make have no effect,

Is there something I can place in additional.css to over ride these style properties? Or where would I go to change this? Thanks in advance, BTW is a custom style, but all else is good, answer is probably right there, but I cant find it, lol, cant see the text in or PM editor, when creating a PM or as well viewing a PM, annoying, lol,

Any help is appreciated,
