Banner color and other 2 questions

Hi, I have three issues here at www.media-dynamix.co.za with Catch-Kathmandu theme: 1. I want to change the color of the blue banner in the footer from blue (1b5f7d) to black (#000000). 2. How can I get rid off the blue banner with the text in the bottom right of featured image sliders. 3. I want to justify the text, I don't see formatting tool, top of the text field in the page area. Many thanks.....
