A red star is fusing mostly hydrogen while a blue star has depleted its hydrogen supply and is fusing helium into heavier elements.
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.
the brightness of a star usually means how close it is to earth and the colour means how hot it is. blue/white being the hottest and colours like red yellow and orange being not as hot.
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.
Simple one is a black-red star and the other is black-blue star. The only difference is the color.

A red star is cool whereas a blue star is hot.
The only difference is the colour of the external shell.
The blue star is the hottest star.

There really is no difference. Maybe different brands made them. But Land-o-Lakes does make both blue and red caps...
