There's no star officially named "Gamma Star". Stars are typically named using Greek letters (alpha, beta, gamma, etc.) followed by the constellation they belong to.

For example:

* Alpha Centauri is the brightest star in the Centaurus constellation.

* Gamma Cassiopeiae is a star in the Cassiopeia constellation.

To determine the color of a star, you need to know its specific name and then look up its spectral type.

Spectral types categorize stars based on their temperature, which directly affects their color. Here's a simplified overview:

* Blue: Hottest stars (O and B spectral types)

* White: Very hot stars (A spectral types)

* Yellow: Sun-like stars (G spectral types)

* Orange: Cooler stars (K spectral types)

* Red: Coolest stars (M spectral types)
