The relationship between temperature/color and expected lifetime in stars is tied to their mass. High temperature, blue stars are typically more massive and burn through their nuclear fuel much faster than low temperature, red stars. Because of this, high temperature stars have shorter lifetimes and will die first. Their massive cores burn through hydrogen fuel at a faster rate, leading to shorter lifespans compared to lower temperature stars. Eventually, high temperature stars will exhaust their fuel and undergo dramatic changes, such as becoming supernovae or collapsing into black holes, while lower temperature stars will continue burning steadily for much longer periods of time.
