How to change search form parameters in WP?

Hi guys,

Just trying to set up my first WP blog at www.hardgainersguide.com.

I found a template I liked, and sort of just started replacing graphics with my own, and changing colours specifically. I added the Search widget on the right sidebar, but can't seem to find the code to change the colour of it? Any idea where I should be looking?

 

The colors seem to match your site fine...

 

You should find the color profiles in the css of your theme, under search form
