Luster is not a color, but a visible characteristic of the mineral's reflection of light off it's surface. In this case, the color of biotite is dark brown to black, but it's luster would be described as vitreous or glassy.
Lead has a metallic luster and is white in color. Aluminum, copper all also have metallic luster. Minerals do not have any metallic luster.
A diamond is the hardest natural substance, scoring a 10 on the Mohs scale. It has a brilliant luster due to its high refractive index. The streak color of a diamond is colorless, as it does not leave a streak on a streak plate.

No, luster refers to the way light interacts with the surface of a mineral, like metallic or non-metallic. The true color of a mineral is determined by its inherent chemical composition.
Iron has a metallic luster, appearing shiny and reflective when polished. It has a silvery-gray color in its pure form.

The four properties of minerals are color, streak, hardness, and luster. Color refers to the outward appearance, streak is the color of a mineral when it's powdered, hardness is the resistance to scratching, and luster describes the way light reflects off the surface of a mineral.
