Which color star is coolest?

Explanation:
Color tells us about a star’s surface temperature: cooler stars glow with longer wavelengths, which we see as red light, while hotter stars glow with shorter wavelengths, appearing blue. White and yellow stars fall in between, with yellow like the Sun being mid-range. So the red star has the coolest surface temperature among the options, which is why red is the coolest color shown.
