The red colour means that it's surface temperature is cool < 3,700K.
At that temperature, the spectrum of light is red.
It is red. Betelgeuse is called a red hypergiant, which is nearing its death.
Betelgeuse is located in the Orion constellation and is a red star. Red stars are generally the coolest of stars.
The red color of Betelgeuse indicates that it is a cooler star, emitting light at longer wavelengths in the red spectrum. This color indicates that Betelgeuse is a massive, aging star that is nearing the end of its life cycle.
The color of the supergiant star Betelgeuse reveals its stage in its life cycle. Betelgeuse appears red because it is a cool, aging star that is at the latter stages of its life, in the red supergiant phase.
It's a fairly cool star

A red color, in a star, is associated with a low surface temperature.
Sirius and Betelgeuse are both bright stars in the night sky, but they differ in size, color, and temperature. Sirius is a white star, while Betelgeuse is a red supergiant. Betelgeuse is also much larger and cooler than Sirius.
It is a Red Giant.
No, Betelgeuse is a red star.
Betelgeuse is one of the prominent stars in the Constellation of Orion.It is actually ORANGE-RED in color.It belongs to the spectral class K ( with temperature 4,900 - 3,500 degrees Kelvin )Betelgeuse is a semiregular variable star located approximately 640 light years from the Earth.It has a spectral type of M2 and a temperature of about 3,500K which means it has a colour of red.
Rigel is a blue-white star, while Betelgeuse is a red supergiant star.
No, Betelgeuse is a red giant.
