TinyMCE 7.00.07 background color

Add in styles.css
[syntaxhighlighter brush=css,first-line=1,highlight=0,collapse=false,html-script=false].mceContentBody {
background-color: #fff /*The color*/
}[/syntaxhighlighter]

Thanks but... it doesn't work ? :/

Hmmm... clear browser cache, put the code at the bottom in styles.css of the theme you are using. If still doesn't work try
[syntaxhighlighter brush=css,first-line=1,highlight=0,collapse=false,html-script=false]body.mceContentBody {
background-color: #FF0000 !important; /*change color*/
}[/syntaxhighlighter]

it doesn't work : /

You are doing something wrong... or i understood you wrong.
Is that color you wanna change? If yes, you are doing something wrong.

yes. i want to change this color....

// this is my color now .... i want to change it because this is bg of web ....

Well, I didn't know you use an image as background. This should work:
[syntaxhighlighter brush=css,first-line=1,highlight=0,collapse=false,html-script=false]body.mceContentBody {
background: none #FF0000 !important; /*change color*/
}[/syntaxhighlighter]

thanks so much !!! it works ! ;))

It was a theme BG image, bug somewhere in TMCE styles - same things with joomla themes.
