Why is Pluto brown?

As pluto has no atmosphere, its color must come from the terrain directly. The probe New Horizons is set to fly by Pluto later this year (2015) and early pictures show it being a relative uniform brown. To be honest, astronomers aren't exactly sure why it's so brown, considering Pluto is mostly made of ice. We'll find out soon!
