Proxima Centauri is a red dwarf star, so would it appear red from the surface of an Earth-like planet in that star's habitable zone?

Astronomers haven’t found planets around our Sun’s nearest neighbor, the red dwarf Proxima Centauri. But there’s good reason to keep looking. Most exoplanets orbit red dwarfs — the most common and longest-lived type of star. Astronomers believe as many as half might have rocky planets. And Kepler spacecraft data imply perhaps 6 percent could have Earth-sized planets in their habitable zones — the region where liquid surface water can exist. That prevalence gives hope for life in the cosmos.
