Julios,

Well, the simplest answer to your question is that stars come in several colors, and that the color of a star is related to its temperature. The colors in order from hottest to coolest stars are as follows:

Blue
White
Yellow--(like our own Sun)
Orange
Red

The hotter a star is, the higher the average frequency of the light it shines will be, and the more energy it will radiate. In the visible light range (in other words, stuff we can see), blue has the highest frequency and red has the lowest.

Hope this helps,
