When we talk about eye color, means the color of the iris. It depends on the amount of coloring pigment – melanin and the thickness of the shell. Since the same melanin responsible for skin color and hair, common color combinations is blue-eyed blondes and brown eyed brunettes – we owe it to him.
The iris works like the diaphragm, it contracts and expands in response to light. When changing the pupil size, the pigments in the iris or focus and the eye darken, or dispersed and eyes are lighter. Because when you are having some strong emotions - fear, love, anger – your pupil also expands or contracts, eye color may depend on your emotional state.
In order to understand what color your eyes are, you have to be in a smooth mood and see them in moderate daylight. If you have light eyes – grey, blue, marsh green, you need to wear on top of that neutral colors to outerwear did not give your eyes extra shade.
We distinguish eight basic colors of iris blue, light blue, gray, green, hazel, amber, brown and red, the albino. And countless shades. Scientists use a scale, Martin Schulz, in which eye color is divided into 16 classes. On this scale exist:

I. Dark eyes

A. dark-Dark 1 through 4 positions on a scale.

B. Dark mixed, with a small admixture of light pigment. 4 and 6 position.

II. Mixed.

From 6 to 12 position. It will be bright eyes mixed with brown pigment.

III. Bright eyes

From 12th to 16th position.

A. Bright-light (grey, blue, green)

V. Light mixed

1. Light-light mixed (blue with gray or green with grey)

2. Light-dark mixed (with a very small admixture of brown pigment)
If you want to know the eye color on a scale, Martin Schulz, then you should contact the Institute of anthropology. There is a special program that reads all the shades of iris in a very high resolution of 100 dpi, and klassificeret eye color with mathematical precision.
Another way to find out what your eye color or to assume with high probability what it will be like your child, is to construct an algorithm, based on the eye color of the parents. Modern genetics have proven that pigmentation is controlled by six different genes that interact with each other in co-dominant, dominant-recessive and dominant –negative scheme.

Light blue eyes have zero dominant alleles.

Blue – one dominant allele.

Blue – two dominant alleles.

Dark green three dominant alleles.

Light brown four dominant alleles.

Brown five dominant alleles.

Kari – six co-dominant alleles.

So, if the eyes of both of your parents light blue, you can not be the owner of the brown eyes.

Since to calculate all this is difficult enough, easier to use online calculators, which there is a great variety.
