Knit w/ 1 color in each hand

I am working on one of my own designs and am finding that my way of changing colors in a row is taking me an awful long time so I would like to know how do you knit by holding one color in each hand? I am using a circular needle and am right handed ( I control the yarn with my left hand ) I am not sure if there is a name for that method but I taught myself how to knit so that is why I am a little different than others.I just couldn’t seen to get the methods the book taught.Any advice?
