Quick Reply Smley Box Background Color

In this screenshot you can see the quick reply smiley box and the white background it has. I would like to change that background to black. The other regular smley box for the "Post Reply" messages the background is already black, but the quick reply is white. I need a CSS code to make the quick reply smiley box background black. thanks

css code :

Code:

#sel_smilies {background:#000000}
#sel_smilies button{background:transparent}

#000000 <~ background color

Thanks it worked, only problem is the background of the emoticons was no longer transparent it showed the emoticons background color as white. This is similar to the Memberlist avatar display as it will show the background color of an avatar as white if it has transparent rounded edges or simply a transparent background. I'm not going to use the code as it is, unless there is a way to make the images keep there transparent backgrounds.

Does anyone have a solution to this?
