Red Heart Super Saver Bitty Stripes has what appears to be watercolours within the ball. I was curious to mix up 4 different colours of this yarn to see the results. 
 
Each colour segment between the 2-rows of Moonbeam (cream) has only 3-rows. Put the ball aside and jump to the next colour. Every 3rd colour stripe continues the ball, though it may not look like the same stripe. 
 
My goal was to use only 1 ball of each colour, but you can extend your crochet journey to make this even bigger.
