It's temperature.
Blue = hot, red = cool.
The relationship is that the color is an indication of the star's surface temperature. For example, red stars are cooler, while blue stars are hotter. You can find more details in the Wikipedia article "Stellar classification".
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.
Not necessarily. The color of a star does not directly correspond to its age. Stars can be yellow at different stages of their evolution, depending on factors such as their mass and composition. The age of a star is typically determined by factors like its location on the Hertzsprung-Russell diagram and its position in a star cluster.
the color of the star regulus is blue-white
The color of Bernard's the star is red.
The color is basically an indication of its surface temperature.

Stars are blue because of their age and temperature. Blue is an indication of a young HOT star, when reddish color means the star is aging

The star's temperature. The more blue the star is the hotter it is. Pure blue stars get up to around 18,000 k. The more red the star is the cooler it is. Pure red stars can get up to around 2,500 k. White, yellowish color stars are in the middle.

No. The color is only an indication of what flavor it is, nothing more.
