I use their blueberry/pomegranate and black magic. The blueberry/pom mixture is lighter colored than the black magic or any of thier "tobacco" flavored blends. However, I am not sure that the color of the
juice is the major culprit in the gunking up of the coils. It may have more to do with the ingredients in the juices rather than the color of the
juice itself. I base this only on my experience with different colors of
juice versus the time it takes the coil to gunk up.
