they are differ by their color
they are also differ in temperature
Blue stars are hotter, larger, and more luminous than red stars. They have shorter lifespans due to their high energy output. Red stars are cooler, smaller, and less luminous, and they have longer lifespans.
A red star is cooler and has a lower temperature compared to a blue star, which is hotter. Red stars are typically older, while blue stars are younger. The color of a star is determined by its surface temperature, so these differences in characteristics between red and blue stars are consistent.
Not necessarily. The color of a star is determined by its temperature, with blue stars being hotter than red stars. Size can vary independently of temperature, so a blue star can be larger or smaller than a red star.
A blue star is hotter than a red star. Blue stars have higher surface temperatures, typically exceeding 10,000 Kelvin, while red stars have lower surface temperatures, usually below 4,000 Kelvin. The color of a star is an indication of its temperature, with blue stars being the hottest and red stars being the coolest.
The color of a star is influenced by its temperature, with blue stars being hotter than red stars. Therefore, you could conclude that the blue star is hotter than the red star. Additionally, blue stars typically have shorter lifespans than red stars.
The color depends on the star's temperature. For example, a blue star is hotter than a red star.

A star with a spectral class of O is classified as a Blue Star. A red star will have a spectral class of M See related question
red and blue light differ in wave length because blue lights have shorter wave length than red light and shorter wave length are good for plants germination.
The blue star is the hottest.
