Navigation Active Link Color

I am using the theme builder for my webpage's navigation.

I would like the active link color to be different on eachpage.

For example homepage has an active link of yellow. Then when you click on About, the color is blue, etc.

How do I accomplish this?

Thanks!

 

Hmmm... I don't think this is working....

I should note that the navigation is in the global header. I edited it in the theme builder.
