The purpose of this SDSS project is to introduce students to the color classification system and its importance to astronomy. A complete review is done on the magnitude scale and how it leads to colors. Then a link is made between the light recieved by telescopes and the temperature of the source. Finally, color-color diagrams are introduced as a tool to verify if a star is a perfect thermal source, since radiation curves can be deceiving.
