A supergiant star can have different colors depending on its temperature. A hotter supergiant star will appear blue or white, while a cooler supergiant star will appear red or orange.
There are many red super giant stars. The most noted in the Northern hemisphere is Betelgeuse, the top left star in the constellation Orion.
that depends on how large the red or super red giant was. if it was a super red giant that is 1000X larger than a red giant. it will become a black hole
