Okay, leave the temperature at this maximum value. Zoom the vertical axis so it reads 0 to 2500. Zoom the horizontal axis so it reads 0 to 1.5. Voil! You're looking at the radiation profile (also known as the blackbody curve) for a star with a really high surface temperature! You are also witnessing the linkage between temperature and color! Slide the temperature control back and forth between 0 and the maximum possible temperature. While you do this keep you eye on the star color indicator. No go back to 11,000 K. This star spews out a rainbow of visible colors, and invisible radiation as well. However, to our eyes this star would appear mostly
