A few questions from a beginner

1.) Is there any way I can set the slider to rotate randomly through the featured images? I take a lot of pictures and would like it to rotate through my newest post's featured images. 2.) I'm trying to change my color scheme, can I change the highlight color of the posts and other clickable info? Currently it's blue and I'd like #F2A070 3.) Also to do with color, I'd like to change my fixed menu bar to #F2A070 as well. Thanks! Bailey theecodiaries.com
