* Hottest Stars: Blue (and even bluish-white)

* Medium Temperature Stars (like our Sun): Yellow

* Coolest Stars: Red

Why the Color Difference?

The color of a star is determined by its surface temperature. Here's how it works:

* Hot Stars: Very hot stars emit a lot of energy in the blue and ultraviolet parts of the spectrum. This is why they appear blue.

* Medium Stars: Stars like our Sun have a surface temperature that emits a good amount of energy across the visible spectrum, leading to a yellow appearance.

* Cool Stars: Cool stars emit most of their energy in the red and infrared parts of the spectrum, making them appear red.

Think of it like a piece of metal:

* A piece of metal heated to a very high temperature glows white-hot, then blue-hot.

* As it cools, it transitions to yellow, orange, and then red.
