The visible spectrum, as it goes from red to blue, refects higher energies and shorter wavelengths, that are produced by progressively higher temperatures. So, bluish stars are hotter than reddish stars.
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".
Blue stars are the hottest, and red stars the coolest. Our sun is orangey, so it's kinda in between blue (hot) and red (cool).
By their color, primarily. There is a very strong correlation between the stars color and it's temperature.
The color of a star is directly related to its temperature. Hotter stars appear bluer, while cooler stars appear redder. This relationship follows a pattern known as the "temperature-color sequence," where stars of progressively higher temperature transition from red, to orange, to yellow, to white, and finally to blue. Therefore, star color can provide valuable information about their temperature and evolutionary stage.

The color of stars determines temperature. Red/brown stars are cooler, blue stars are hotter, and yellow stars are in between. Brightness also has some correlation with color. Both are based on many varying factors however.
the color of stars with the lowest surface temperature is red

Brightness tells you the temperature and mostly temperature would tell the brightness of the star that we are talking about.
The Color of stars depends upon their surface temperature.
as surface temperature increases, luminosity increases

you can tell the temperature by its color
