Why Do We See Different Colors in the Same Star?

Stars look different colors because they're like fire in the sky, some are hot and bright, others are cooler and dimmer. Just like a campfire is red when it’s low and blue when it’s high, stars show us their color based on how hot they are inside. The hotter ones glow blue or white, while the cooler ones look yellow or even red.
