The amount of pigment in the eyes
the colour spectrum works like this ranging from the least amount of pigment to the most amount of pigment
red/pink (albino's), violet (also present in albino's, debatable existence in non-albino's), blue, grey, green, amber, true hazel, brown, black/very dark brown (non-caucasians)
Amber is the center of the eye colour spectrum being the lightest brown eye, so all eyes darker than amber are closer to black/very dark brown and all eyes lighter than amber are closer to blue.
However red/pink isn't really an eye spectrum colour due to it only found in albino's (because they have no pigmentation and you're seeing the blood vessels at the back fo the eye) and people with blood leakages in their eye, and violet (very rare) and grey are both shades of blue, and amber, true hazel and black/very dark brown are all shades of brown, so technically there are only 3 true eye colours, blue, green and brown, the rest are basically significantly different shades of the 3.
note: true hazel eyes are a light golden brown colour (basically light brown) they can contain minimal green (either within the gold and/or around the edges of the eye) but green is by no means a requirement for true hazel eyes. True hazel eyes are not just any eye that contains both green and brown in the same iris. If you class hazel eyes as being green with brown then they come under the green category and are therefore lighter than amber.

Are there more brown eyes than blue eyes?
not necessaryly. The more melatonin you've got in your eyes, the darker is its color. Now, with dark eyes you're best prepared for locations where the sun is shining bright, cause there won't pass as much light to your retina as if you had blue eyes. On the other hand, people with blue eyes have an advantage in areas with dim light, because their iris lets more ligth through and so they may be ready to see light where people with darker eyes still can't do so. In short: In Africa people profit from brown eyes wheras people in Skandinavia do so with blue eyes.
