Color change in crochet?

Hi all, I am brand new to Crocheting, trying to teach myself. I am working on a pillow pattern that has contrasting color blocks and cannot for the life of me understand the color change process. Every instruction I have read indicates to carry the yarn over on the wrong side. I get that concept but can't understand how to do that when I am working with the wrong side facing me. How do I get the yarn neatly to the wrong side when it falls to the back? I hope this question makes sense, I have redone these rows about 5 times trying to figure this out and it just isn't working for me :-) Video might be nice!
