Compared to the surface of the Moon, how does the material that makes up a comet generally appear when reflecting light?

Answer

Generally much darker

The material constituting a comet is typically much darker than the lunar surface, meaning it reflects very little light until the ices begin to sublimate and create a brighter coma.
