The "color" of anything is determined by the wavelengths of visible light that are reflected off of it's surface. When that reflected light reaches your eye, you see color. The colors you don't see are those that are asborbed by said material. Some materials emit their own light however, in which case, those emitted wavelengths would combine with those that are reflected.
Because some minerals have either multiple colors or their color may have faded away over the years
Because many different minerals have multiple colors like the sapphire has like 5 different colors and the colorless one looks almost = like a diamond so you can't really classify by color. miss myself for ever: some minerals color is changes from time and weather
Fluorescent minerals absorb light energy and re-emit it as visible light in different colors. When light shines on them, they become energized and glow with vibrant colors.
Relying solely on color to identify minerals can be the least useful method, as many minerals can have similar colors but different compositions. This can lead to misidentification and confusion.
It often does not match the observable color of the specimen. Differences between streak and observable color can be due to inclusions, staining, refraction, impurities, or exposure to heat and radiation.

When you look at a rock and see different colors, those colors are minerals .The pressure and heat causes the minerals in the rock to change into different minerals which cause the different colors in the rocks.
Basalt consists of multiple minerals. Pyroxene, calcium-rich plagioclase, and sometimes olivine are key minerals in basalt. Basalt that cools rapidly may form glass, which contains no minerals because it lacks a crystal structure.
yes
Gabbro is usually made up of minerals such as pyroxene, plagioclase, amphibole and olivine which makes it an intrusive igneous rock.

Most minerals are compounds, made up of two or more elements. Very few minerals are composed of only a single element, such as native copper or gold. The majority of minerals form through complex chemical reactions involving multiple elements.
The color is derived from the chemical composition of the mineral, or from staining or inclusions of other minerals.
yes
From the different minerals the animals feed on
Ex.: emerald, mallachite, chrysoberyl
brown is a fusion of multiple colors arbitrarily mashed together, thats why it tends to be ugly and that is also why anus spooge is brown.
