The video tutorial discusses the mineral composition of igneous rocks and how it relates to their color. It covers different types of igneous rocks, including felsic granitic, intermediate and acidic, mafic basaltic, and ultramafic rocks. Each type is characterized by specific minerals and colors, such as light-colored quartz and potassium feldspar in felsic rocks, intermediate colors in rocks with hornblende and plagioclase feldspar, dark colors in mafic rocks with hornblende and augite, and green shades in ultramafic rocks with augite and olivine.
