Why might sand on beaches in Hawaii be different colors even though the sand all formed from igneous rock?

n Hawaii you can find black sand beaches, because the sand comes from eroded basalt - lava from the volcanoes. ... That sand is made of olivine, an igneous rock that is rare on the surface of the earth because it breaks down up here, and is stable inside the earth (where the pressure is higher and the temperature hotter.)
