The color of a star is closely related to its temperature. As the temperature of a star changes, so does its color. This relationship is described by a principle known as Wien's law, which states that the wavelength at which a star emits the most light is inversely proportional to its temperature. When we talk about the color of stars, we often refer to their spectral classification, which is a system that categorizes stars based on their temperatures and spectral features. The most commonly use
