Red from all data I have looked at.
The coolest stars are red in color. They are classified as red dwarfs and have surface temperatures ranging from about 2,500 to 3,500 degrees Celsius.
Orange is the coolest color of stars
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.
Red stars have the coolest surface temperature. Blue color stars have the highest surface temperature. The Sun belongs to the main sequence stars.
the color of stars with the lowest surface temperature is red
The Color of stars depends upon their surface temperature.
All stars are hot. Their temperature can be determined by their color. The "coolest" stars are red in color. As temperature increases stars will go through orange, yellow, white, and finally blue for the hottest stars.
the color of stars with the lowest surface temperature is red
A cool star typically appears red in color, as it emits lower-energy, longer-wavelength light compared to hotter stars. The surface temperature of a star determines its color, with cooler stars producing reddish hues.
Betelgeuse is located in the Orion constellation and is a red star. Red stars are generally the coolest of stars.
Massive stars can appear in a range of colors depending on their surface temperature. They can range from blue (hottest) to white, yellow, orange, and red (coolest). The color of a massive star can provide clues about its temperature and stage of life.
Red stars have the lowest surface temperatures.
