Change color of black menu bar

Hi, I use Fotografie free for my 17 year old daughter's site: http://nabeleving.nl. I would like to change the color of the black menu bar(s) to the color of the background of the footer: #e1ad86. I can't find the solution. Some CSS codes seem to work on other Catch-themes, but not in this theme. She can't afford the pro-version. Can you help me with a CSS code that override other definitions? Thanks in advance! Henk
