Answer :-
Because of the dominance of oxygen and silicon in the crust, igneous rocks are mostly made up of silicate minerals. These silicates can be generally divided into light and dark silicates. The dark silicates are also called ferromagnesian because of the presence of iron and magnesium in them.
some more information:-
why are igneous rocks dark?
The color distinction comes from the differences in iron and magnesium content. Iron and, to a lessor extent, magnesium give minerals a darker color. Intermediate igneous rocks tend to have intermediate shades or colors (green, gray, brown).
what light colored igneous rocks called?
Pumice is a light-colored vesicular igneous rock. It forms through very rapid solidification of a melt.
