[SOLVED] Change current page menu bar background color

I would like the "HOME" and "FEATURED" tabs (FEATURED is a static home page) to have a #ffffff background and match the background of the page menu bar when visitors are currently visiting that page.

I have tried what feels like a thousand different CSS inserts but I'm not sure what CSS insert I need. Any ideas anyone?

div#menu1 ?????????? {
background: #ffffff;
}
