Change "Latest Activity" background Color

[MokeyII]

I've been searching on how to change the color of the "Latest Activity" Feed Background Color.

I can't seem to find a stylevar, and it's driving me up the wall.

I want it to a grey color I have chosen, because the white just looks atrocious with the color scheme I am going with.

Any help?

In css_additional

#activity-stream-tab .conversation-list.stream-view .list-item {
background: #cccc; /* change color accordingly */
}
But you have to also change other elements (probably including icons) that are gray, otherwise, they would be invisible.
