CSS for testimonial box with two colors

A wp designer set up my site using Thesis – and BYOB plugin to create testimonial boxes within content area. That plugin doesn’t work with a multi site.

I’d like to create a testimonial box with CSS and HTML or plugin (that works) that has a title area with one background color, and below it the testimonial text with a different background color.

Any ideas or pointers?

I can setup a box with one color – it’s getting the second color for the title that is a puzzle.
