Although purportedly all over the web, I just now saw this!  Scientists have discovered pigmentation by studying the melanosome patterns in living birds.  Using these findings, they’ve accurately figured out the color of a 150-million-year-old species called Anchiornis huxleyi, about the size of a chicken.  According to the New York Times,

Anchiornis had a crown of reddish feathers surrounding dark gray ones, and its face was mottled with reddish and black spots. Its body was dark gray, but its limb feathers were white with black tips.

I can’t wait to see what amazing colors other dinosaurs might have!
