In a child, eye color can change during the period of his first year of life, especially in blondes. Most babies are born with blue-gray or bluish-gray eyes. By about 6 months, it becomes clear what the final eye color will be. Children with dark skin at birth usually have dark gray or brown eyes. Eye color is most often determined by parental genes, but even a great-grandmother or great-grandfather can make unexpected contributions.

Step 1
Eye color is a fascinating and interesting topic that has captured many researchers for several centuries, until science helped to better understand the origin of eye color, and most importantly, how it is inherited. When it comes to predicting the color of a baby's eyes, one thing is certain: the baby will be born with blue eyes. Almost always, the eyes of newborns have just a blue color, which can subsequently darken as the sun is exposed to it. By about 3-4 years of age, the baby's eyes usually acquire their formed and permanent color, which remains for life, be it blue, amber, gray, green, hazel or dark brown.
Step 2
Eye color inheritance is scientifically possible. There is a well-established belief that baby's eye color is inherited according to Mendel's laws. Consequently, according to this law, eye color can be inherited in almost the same way as hair color: the dark genes are dominant, that is, the distinctive features (phenotypes) encoded by them will take precedence over the distinctive features that are lighter in color.
Step 3
It is most likely that parents who have dark eyes (brown) will also have children with dark eyes. Accordingly, the offspring of parents with light eye color will also have light eye color, and the baby of parents with different eye color will have an eye color that is more dominant. For example: dad has light green eyes, and mom has blue eyes, in this case, the child's eyes may be 60% blue and 40% green, since blue is the dominant color. At the same time, brown is considered the most common eye color around the globe, and green is considered the rarest eye color.
