Yes, it is! You might also notice that people with brown hair typically have brown eyes.
Skin color also often fits in this trend: people with lighter hair and skin often have light eyes. And people with darker hair and skin usually have dark eyes. The color of our hair, skin, and eyes is determined by the same thing: the amount of pigment they have. The pigment that causes dark hair, skin, and eyes is called melanin.
Melanin is made in special cells in the body called melanocytes. But you asked about blue eyes specifically, not just light-colored ones. Well this gets into why we only see brown, blue, and green eyes typically.
The iris of your eye the colored part is where melanin can be found. People with dark eyes have a lot of melanin in their iris. This dark melanin pigment makes the eyes look brown. And since melanin can absorb light, they look even darker!
This blue color is made by light scattering when it hits blue eyes or the sky or ocean! The blue color in eyes and water is made by scattering light Image from Pixabay. An iris with a lot of melanin absorbs light, making it appear darker. And an iris that has some melanin will absorb some light and scatter the rest, making it appear green. Green eyes have some brown pigment that absorbs some of the light and scatters the rest Image from Flickr.
The production of melanin is determined by your DNA. We generally talk about different traits as independent. For example, whether you are tall or short does not affect if you need glasses! But the genes for eye, skin, and hair color are different.
This is why people typically have either all light features, or all dark features. If one parent has a darker complexion and the other has a lighter complexion, then their children could have a mix of light or dark hair, eyes, and skin. Parents with different complexions can have kids with intermediate colors Image from Flickr. Imagine if there was a region where most people had lighter complexions. As the population grows and people have babies, the genes for less melanin will become more common.
That makes the link between lighter eyes, hair, and skin tighter.
