Red stars have the lowest surface temperatures.
Black dwarfs have the lowest surface temperature.
Red stars are the coolest of the stars.However, for completeness:A brown dwarf is cooler.A white dwarf can be the hottest and one of the coolest (Depending on age)A black dwarf is the coldest.
Yes, they have roughly the same surface temperature. Internal temperatures may be very different depending on the respective stages of stellar evolution the stars are in.
Phoenix is a constellation, not a single star. The constellation contains a very large number of stars and other cosmic objects which have no astrophysical relationship with one another. It is simply that they are located in such a direction, and are so far away, that they appear to move together. The different objects vary enormously in their colour and surface temperatures.
A star's color is caused by the type of gases its made up of and the temperature. The temperature changes depeding on the age of the star. Older stars turn red due to the amount of space it has to heat up.
the color of stars with the lowest surface temperature is red

The Color of stars depends upon their surface temperature.
its surface temperature
red
yes, red stars are the lowest in temperature, while white stars are the hottest. Their age may also effect their color though.
By their color, primarily. There is a very strong correlation between the stars color and it's temperature.
Red from all data I have looked at.
Its brighter so has blue colour
The color of a star depends on its surface temperature. But hot stars are blue, and medium-hot stars are white, and cool stars are red.
