Changing the Six theme colours and fonts

[charliem]

Hi, 

I am trying to change the six theme colours and fonts, I have managed to change the navbar colour by using the custom.css sheet.

.navbar-main,
ul.top-nav > li.primary-action > a.btn,
.btn-primary {
    background-color: #E4B062
}

Thats the code I used, but I only found that off a community post on here.

How do I find out how to edit different sections and not just the nav bar? I don't know how to identify what section is which.
