Page menu background color : 2 colors possible?

Hi there!

Is it possible to have 2 background colors on the page menu?
I know a single different color is possible, but I need to sort 2 kinds of content : editorial and products. And of course, I'd like to differenciate these two contents.

What I'd like is :
editorial : white text / gray bg
products : white text / red bg

Thanks ^^
