Brown (all shades, including black) eyes are dominant, and hence most common.
Blue are recessive to brown.
True green is recessive to blue.
And there you go.
OT: My eyes appear dark blue from a distance. Up close there is an very dark ring around the edge. The inside is a multitude of blue flecks, ranging form practically black to practically white. I also have a greenish/brownish smudge/spot on my right eye sitting on the top left of my pupil, it's usually not visible because of my eyelid.
