Pumice can vary in color from white to gray to black. Much of it has to do with the chemical composition. Felsic varieties are most commonly light in color. Mafic varieties can be darker in color.

What is pumice feel like?
Pumice, an igneous rock, is generally white to dark gray.
What is the cleavage of pumice?
Pumice is a disordered material, a result of quick freezing of a boiling glass, and is irregular in all directions. It has no preferred cleavage direction, and indeed is not classed as a mineral, for it lacks both a single chemical form, and a defined crystal arrangement. The pumice with which I'm most familiar is white to light yellow, but depending on the source material, it will be darker as the magma component is increased. Scoria is a more magma-rich form, and is denser than the white variety.
