Does anyone know a way to change the background colour of my wiki's slider? I tried to edit it by finding its coding in the MediaWiki, but nothing helps.

Here is a link to one of the sliders: http://wargameeuropeanescalation.wikia.com/wiki/Template:Wikiportal:Main/Screenshots. I want to change it's brownish-yellowish background to fit my wiki's theme.
