Editing the menu color – Theme Go Daddy Cleanio

I am using the Cleanio theme for the first time with a customer who likes the black background, but not the red menu bar the comes standard with it. I don’t find a simple menu option to change the menu color. Where do I find the code to edit the menu color? What we would like to achieve is a white (or very light grey menu as shown with the blue standard background). When a page button is depressed, we would like to be able to change the color that the button turns.

First time using WP so please be kind with your instructions. I’m using a temporary web address: 666.434.myftpupload.com because the client has an existing site that we don’t want to disturb until this one is finished.

Thanks for your help!
