The hottest stars are blue-white in color, followed by blue, white, yellow, orange, and red. The coolest stars are red dwarfs.
The color of a star can also be affected by its age and metallicity. Younger stars tend to be bluer, while older stars tend to be redder. Stars with higher metallicity (i.e., more elements heavier than hydrogen and helium) tend to be bluer than stars with lower metallicity.
The colors of the stars in a constellation can create a beautiful and striking pattern in the night sky.
