Changing font color in a single widget

Hi
I wanted to have a menu-like list of pages at the side (not necessarily a sidebar – just a 1/4 layout element). I couldn’t see a way to do this so I used a plugin called Flexi Pages Widget which works fine but doesn’t include nice styling options.

My question is:
How can I change the font color of the bullets and links in this widget/element only? I want them to be white but the other links on the site should be orange. I don’t want to effect all other links in the site.

I give the specific page URL and login details in the private content so you can have a look.

(Of course you may also be able to suggest another way to achieve this custom sub menu list without the plugin but I would still need the styling fix.)

Many thanks
Tia
