Stars can look different colors because they are like big, hot fireballs. The ones that are really hot appear blue or white, while the cooler ones glow red or orange. It's just like how a campfire is orange and a light bulb is bright white.
Examples
- A red star looks like a glowing ember from a fire.
- The sun appears yellow because it’s just the right temperature.
