How Common Is Brown Hair and Blue Eyes?
Eye color is one of the most fascinating aspects of our appearance. We all have a unique eye color which is determined by genes. It’s always interesting to look at the different shades of eye color that different people have.
Brown hair and blue eyes are not as common as you think. Although they are fairly common in Western societies, they are not the most commonly found eye-and-hair color combination.
These two colors happen to be dominant genes, meaning that if one of your parents was born with these eye and hair colors, there is a high chance that you will inherit them too. However, brown hair and blue eyes aren’t the only combinations possible. Here are some other rare combinations of eye-and-hair colors.
The most common eye color is brown, and the second most common is blue. Brown hair and blue eyes are not as rare as they may seem. Brown hair varies from a light blonde to a deep black, while blue eyes can be sky-blue or more of a grayish-blue.
A person’s hair and eye color can be influenced by their genetics, but it can also be affected by how much sun they get or what they eat. In this article, you will learn about the science behind hair and eye color and why brown hair is so common in the world.
The more common eye-and-hair color combinations
Before we go into the details on how common each hair and eye color combination is, it’s interesting to note that most of the above combinations are nonexistent.
This is because a human with a particular eye color will also have a natural, inherent hair color that is dominant over his or her other parent’s natural hair color.
So a brown-eyed person will have dark brown or black hair, a blue-eyed person will have light blond or brown hair, a green-eyed person will have light brown or black hair, a gray-eyed person will have light blond or brown hair, a hazel-eyed person will have light brown or black hair, and a person with a single-colored eye will have dark brown or black hair.
So for example, a brown-eyed woman with red hair is a rarity. We will now look at how common each eye and hair color combination is:
If brown hair and blue eyes are not your preferred eye-and-hair color combination, don’t worry. These are not the only two colors.
For example, there are also green eyes and black hair, which are much more common than brown hair or blue eyes. Other combinations of eye-and-hair colors are blonde hair with hazel eyes, black hair with brown eyes, green hair with blue eyes, and red hair with green eyes.
So, what do these colors mean?
Hair color is primarily determined by two genes: Eumelanin (brown/black) and Pheomelanin (red). These genes primarily determine the quantity of melanin in your hair.
Eye color is determined primarily by the amount of melanin in the iris. The more melanin, the darker your eye color will be.
These two genes can combine in different ways to give you different eye-and-hair color combinations. But these are not the only colors out there!
Brown hair and blue eyes
Brown hair and blue eyes are not the most common eye-and-hair color combination.
The dominant color genes that are present in brown hair and blue eyes are recessive, which means that the genes for both colors need to be present for you to have these colors. For this reason, they are fairly uncommon.
However, brown hair and blue eyes are fairly common in Western countries, making them fairly easy to find.
There are many other combinations of eye-and-hair colors possible. Some of the rarer ones are hazel eyes with red hair, golden eyes with black hair, and green eyes with blonde hair. Other rare eye-and-hair colors :
- Blonde hair and blue eyes
- Blonde hair and brown eyes
- Brown hair and green eyes
- Brown hair and hazel eyes
- Black hair and brown eyes
- Black hair and green eyes
- Black hair and hazel eyes
When I first looked up this question, I thought brown hair and blue eyes were a fairly common pairing. I was surprised to find that this is not the case.
Brown hair and blue eyes are not as uncommon as people may think, but they are not the most common either. These two colors are dominant genes that can be passed on from one of your parents, but there is a chance it can be passed on from both parents as well.
Brown hair and blue eyes are fairly common in Western societies, but they are not the most commonly found eye-and-hair color combination. Here are some other rare combinations of eye-and-hair colors.
