Angel Baby Knit Baby Blanket Question..

[sonotgraceful]

I know this is like the simplest baby blanket ever but I had a question...the materials say: Red Heart Baby Clouds (6 ounce/148 yeard solid color and 4 1/2 ounce/110 yard multicolor skeins). But the directions never say to switch colors or anything...so do this mean I use both together? Or what? Thanks a lot!!
