Two-color scarf

[Valkyrio]

I just started knitting recently, and I've gotten confused looking at all the results for multi color knitting, so pardon if the answer to my question is easily found:

Is there a relatively easy way to knit something (a scarf, specifically) using two colors? I'm fine with it being a simple stitch. I'm not looking for fancy patterns or borders. However, if there's a simple way to add fringing that would be great too.

Thanks!
