Rigel is actually a triple star system. Rigel A is a blue-white super-giant; the other two are blue-white main sequence stars.
Rigel, or to be more precise, Rigel-A is a blue white super giant which started life with around 24 solar masses. , over a period of around 8 million years it has exhausted its hydrogen and has moved into the blue super-giant zone of the H-R diagram. It is expected to end its life as a type II supernova.
Rigel's temperature is: 11,000 K And the colour is: Blue. To be exact Rigel is a Blue supergiant.
