This is what I would do...

Step 1. Upload it to your site and take a screen shot .... (Ctrl prt screen)

Step 2. Open that SS in photoshop and hit B or I what ever one is the eye dropper...

Step 3. Where ever the color is you want to change take the dropper and click for it.. Then open the colors menu and find the exact #code it is...

After you have done that open the style.css and Ctrl F ...Play around with the #code color till you find the color you like!

let me know!
