Most stars live in the main sequence for the majority of their lives. Our star is a yellow star within this main sequence.

White Dwarfs

The closer to the Y axis, the hotter the star. Thus, white dwarfs and blue giants are the hottest stars.

The further from the Y axis, the cooler the star. Red giants are large, but very cool.​

Temperature

Brightness on the HR diagram increases the further you get from the X axis. Blue and red giants are the brightest stars mainly due to their size; not temperature!
