All types of Eye color!!




Genetics of Eye Color
When it comes down to it your genetics ultimately influences your eye color. While most people consider the basic eye colors to be brown, blue, hazel and green, there are actually many variants. These include:
  • Brown Eyes - The most common eye color in the world. Brown eyes range from light brown or honey to almost black. Light brown (or amber) eyes are common in many ethnicities including among Africans, Asians and Caucasians. Genetically brown appears to be more dominant than other eye colors, hence its prevalence.
  • Black Eyes - People with very dark colored irises appear to have black eyes. This is more common among Native Americans, Africans and Asians.
  • Hazel Eyes - This color combination is a mix of green and brown eyes. Hazel eyes are most common in people of European descent.
  • Blue Eyes - Blue eyes are quite rare and are becoming less common. A few generations ago 30% of those born had blue eyes; now that number has decreased to about one in six. This eye color is often found among people of European descent. It is believed that every person with blue eyes shares one common ancestor. Many consider vibrant blue eyes among the more desirable qualities.
  • Grey Eyes - Grey eyes are a variant of blue eyes, only much lighter. Grey eyes often include a combination of other tints including light blue or greenish. Still others may have a copper or honey colored ring surrounding the pupil of their eyes. This is a relatively uncommon eye color.
  • Green Eyes - Green eyes are among the most rare eye color; only about 2% of people possess green eyes. They are typically found among people with Germanic or Slavic origins. Although green eyes are rare throughout the world, in some countries they are very common. It is said that 80% of people in Iceland have green or blue eyes. Green eyes are much more common in women than in men.
  • Violet Eyes - Violet eyes are much less common than green eyes. Many believe violet eyes result when there is not enough pigment in the eye to color the blood vessels so they shine through causing a violet like color.
  • Red Eyes - This commonly occurs in people who have a condition called albinism and results when the eye lacks any pigment.
