You will be selecting three main colors for your QuickLaunch site, plus a call to action color.
A call to action color is a specific color used exclusively to highlight the places on your site where you most want your viewer to click or take action. This might be a button, a contact form, a link, or a navigation button.
As you can see, the only places where orange is used on this design are the “Sign Up Free” buttons.
