how to change colors

Hi there, I like the theme very much and the main reason to buy kathmandu pro was to have the opportunity to change colors easily. But I could not find options for the following. Maybe I am too stupid?? :) 1.How do I change the background color (Hex #RRGGBB) of the Homepage Headline? 2.How do I change the text color of the Homepage Head- and Subheadline? 3.How do I change the color of the Homepage Button? 4.How do I change the background color (Hex #RRGGBB) of the footer? Thanks for your answer
