Dark blue, dark green, vivid green, and bright gray all in one color. Then i have light green patterns (i don't know what to call them, so "patterns." flecks maybe). And then there's is something overall silvery about them.
Mine are dark brown with a darker ring around them. They're very reflective, so sometimes it looks like they've changed color when really they haven't. But sometimes thy do change color. From chocolate brown, to DARK chocolate brown.
