Why do most stars appear white to the naked eye, regardless of their actual hue?

Answer

Cones, which perceive color, often fail to activate due to the overwhelming faintness of point sources.

Because stars are faint point sources, the human eye's cones, which register color, often fail to activate, causing most stars to appear white, as only the rods register intensity.
