The Intense and Dispersion colors are very similar, the difference is the size of the pigment. The pigments used in Intense colors are smaller. Both of them can be used to tint resin and it remain pretty transparent. It's not the same kind of transparency you'd get if you used inks, it's a bit heavier look than that. Intense colors leaves you with a bit more clarity than Dispersions. The more you add, the more opaque your piece will be of course.
