Unable to set different colours when widget is used twice

Hi!

I have the widget in two different places on my homepage, but although I have set different background colours for each widget, they both sync with each other.

The widget in my sidebar should have a white background and the widget in my footer should have a beige background to match the footer box colour.

Any clues how to change this?

Thanks,
