Different wavelengths of light have different colors.
Color is a characteristic that depends on which parts of the visible light spectrum are reflected from a mineral. Different minerals absorb and reflect certain wavelengths of light, resulting in the colors we observe.
It is the part of a molecule that is responsible for its color. When a molecule absorbs a wavelength of visible light and reflects or transmits others, this is when the molecule's color will appear.
The color of visible light is determined by its wavelength.
Brown absorbs most wavelengths of light in the visible spectrum, reflecting back a range of colors. This absorption of light gives brown its characteristic dark color.
Visible light includes any color that the eye can see.
A red object absorbs most colors in the visible spectrum except for red. Red objects reflect red light wavelengths, giving them their characteristic color.
Sodium nitroprusside is red in color due to the presence of the nitroprusside ion (Fe(CN)5NO), which absorbs light in the visible spectrum region corresponding to red light. This absorption of red light gives the compound its characteristic red color.
Chlorophyll and carotenoids are substances that can absorb visible light in plants. Additionally, dyes and pigments used in various applications can also absorb visible light, leading to their characteristic color appearance. Metamaterials and semiconductor materials are examples of inorganic substances that can be engineered to absorb visible light for specific purposes.
Yes, wavelength is a characteristic feature that determines the color of light. Different wavelengths of light correspond to different colors in the visible spectrum, with shorter wavelengths corresponding to colors like blue and violet, and longer wavelengths corresponding to colors like red and orange.

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.
