Which star is the brightest red or blue why?

Answer 1

A blue star is the brightest, because it is the hottest.

A blue star is about 30,000 kelvin, whereas a red star is less than 3,700 Kelvin

Answer 2

The brightest stars are typically blue because they are hotter and emit more light compared to red stars. Blue stars have higher surface temperatures, which causes them to shine brighter than red stars.
