Mainsheet and jib lines needed

Yup, I've tried the search here but it really doesn't work that well it seems. I am looking to get some new mainsheet and jib lines but not sure what type. I would love to have blue for the mainsheet and red for the jib sheet. Not only will it help me a tad as a beginner but it will help my wife and daughters who want to learn to sail AFTER I learn. So what type?

I would prefer to have at least 3/8" and something not so hard on the hands. I heard several people like the Regatta Braid but I can't seem to find them in different colors.
