1 of my daughters has blue eyes, wife has green, then around 3-4 they turned green. The Mrs was happy she had a fellow green-eyer!
All the rest are blue eyed.

Well, we can all sleep better tonight...
No more lying awake wondering about it...

Green and grey eyes come from the same mechanism. It’s a matter of varying levels of melanin, with green and grey falling in between blue and brown. The gene in question does not have to be entirely off or on - it is already only partially influenced by the mutation (in an adjacent gene).

What about someone that has eye color other than brown or blue

Like Elizabeth Taylor's violet eyes?

LOL interesting.

Friend of mine has her 4 grandparents with blue eyes.
Her parents have brown eyes.
She has brown eyes and her three other siblings have blue or green.

Genes are baffling sometimes.

I had a college roommate with two different color eyes. Also a girlfriend. And also a cat. The roommate, the girlfriend, and, presumably, the cat were all chimeras.

I and all of my children were born with blue eyes. Mine stayed for about a year according to my mother and turned to what they are now - light brown.

My daughter kept her blue eyes for nearly two years but hers are now olive green.

What is the trigger that causes this change?

The Pfizer vax?

I was always taught that it had to do with your exposure to sunlight when you were a baby added to genetic tendencies.
Green eyes are the most rare, followed by Hazel, Blue and Browns.
Eye color is a lot like the ocean, the color is a reflection of the light it gets.
I live in the middle of the Pacific, on a clear sunny day it as blue as can be, but if a marine layer comes in it becomes a grey.
Go figure.

Melanin moves around in the body for about 3 years before it settles.

I do not buy this. When I was a kid, there was a man named Mr. Gartside. He had 4 daughters. One was blonde with blue eyes. One was black haired with brown eyes. One was a red head with hazel eyes. And one had brown hair and green eyes. That blows their premise all to hell. Both Mr. Gartside and his wife had brown hair and blue eyes. It was the craziest thing I have ever seen. All of the children’s hair color and eye color was distinct!

“My Dad has deep blue eyes and my Mom dark brown. I have deep blue, one brother has light blue, another brother has hazel, another brother is dark brown and a sister who has green eyes.

My wife has dark brown eyes. My oldest sons are a slate grey, his little brother dark brown and my daughter has deep blue eyes with red hair.

Heck of a Punnett square to work out for eye colors!”

Your Mom carries the gene for partial activation of the melanin-controlling gene. You and all of your siblings except (possibly) your dark-brown-eyed brother inherited this gene, which has expressed itself differently in all of you. All of you inherited a blue-eyed gene from your father.

Your wife carries a blue-eyed gene. She passed it to your oldest son and your daughter, passing her dominant brown-eyed gene to your younger son. You gave your oldest son the variable gene.

That is the most likely configuration, although there are other possibilities that involve deep blue being an expression of the variable gene in your father as it is in you (your mother still has to carry the blue-eyed gene at least).

“Think if a cave women sees a blue eyed man for the first time. He gets lucky for sure.”

Or they sacrifice him or kill him for being a demon.

Inheritance is in general probabilistic not deterministic. Often inherited characteristics skip a generation or two and might end up somewhat muted.

Also, in your example there might be hiding in that family some interesting “made-for-TV-the-chick-channel-stories” you’re not aware of!
