I haven't tried it but I would put some random swirls of one color, then flood immediately with another color. Use a toothpick to blend the colors.
Let us know if you find a great technique and post some pictures.
You also can flood the cookie first the do your marbling

I flood on the first color leaving some random blank areas, then fill in with the next color. Then I swirl the colors together with a toothpick but I always break off the "sharp" end first. I find this makes the swirls look nicer than doing it the sharp tip of the toothpick.
