Colors of Star
When we look at the majestic clear starry sky, if there is one thing we notice is that some stars are better seen than others in terms of color & brightness. There are shades, but the stars have three basic colors: red, yellow, and blue. Red stars are the coldest and blue or white are the warmest. We can also determine the age of a star by its color. Young stars are hot blue or white, and old ones are relatively cool and red. The color of a star depends on the temperature on its surface, and the temperature on the surface depends on the age and mass of the star.
