Generally, yes. For stars on the main sequence, meaning that they fuse hydrogen at their cores, mass, size, color, brightness, and temperature are all closely related. More massive stars are larger, brighter and hotter than less massive ones. The least massive stars are red. As you go to more massive stars color changes to orange, then yellow, then white, and finally to blue for the most massive stars.

Is the color of a star related to its size why or why not?

Yes, the color of a star is related to its size, primarily due to its temperature. Larger stars tend to be hotter and emit more energy, resulting in a blue or white appearance. In contrast, smaller stars are cooler and appear red or orange. This relationship is described by the Hertzsprung-Russell diagram, which illustrates how a star's color correlates with its temperature and size.
