The color of the star can be indication of the?
The star's temperature. The more blue the star is the hotter it is. Pure blue stars get up to around 18,000 k. The more red the star is the cooler it is. Pure red stars can get up to around 2,500 k. White, yellowish color stars are in the middle.

Which star is hotter a red star or a blue star?
a blue star is hotter then a red star because it is younger and thus has more energy. a good example of this is when you look at a flame on a lighter you see blue light at the bottom because blue is hottest and closest to the heat source whereas the red-orange flame at the top is farther away from the heat source and thus is not as hot as the blue.
Why are blue stars hotter than red stars?
It's because of the temperature of the star. The temperature defines the colour of the star. A red star is cooler than a blue one. Imagine heating an iron rod. It will start off black, then red, then orange, then yellow and if you continue heating it, it will turn white. If you could heat it a lot more it would turn blue.
