Hi
if you want to change only the Masthead blue color
you can open template css folder /custom.css file and add this code
div.ja-masthead {
background: linear-gradient(135deg,#611eeb,#9c4ff0);
}
change the background gradient values as per needs. If you want to customize complete Theme, i suggest you to use Theme Magic too in template style options : http://www.t3-framework.org/documentation/customization.html
