Thank you again. So what is the average surface temperature of a red giant?

As far as I think,talking about the avg surface temp. of the RED GAINT will not proper as the surface temp is much different from the core temp. But taking overall view as it was stated I consider the avg temp to be anywhere between 4000-5000 temp.
