Yes... pour your accent color(s) into your base color, and give it a couple figure 8 swirls with a stick. Don't over mix it. Then pour it out with a bit of pattern to your pour. Use LOTS of resin. Epoxy swirls don't get the color separation you get with poly. That's just how it is. They tend to blend together a bit no matter what you do. But you can still get decent results... just not like you get with poly.
