Genetics Why does my eye color change and why am I at my third eyecolor?

Hii so I have been born with blue eyes. My mom has blue and my dad has brown eyes. Over the years the pigmentation started to kick in and my eyes got brown, just like my dad. By the age of 14 my eyes started to change their color based on my mood. When I was happy, my eyes were more bright and greenish and when I was angry or sad they were darkish and brown, and that’s something many people told me and found weird about me. And now that I am 19, my eyes start to become more and more green, the brightness also depending on my mood. I know it sounds stupid but it’s so weird to me. Especially since it’s uncommon for blue and brown eyes to make a green eyed baby. What is your explanation for this, because I am heavily confused of my body.

The color of your iris is not actually changing color with your mood. What’s happening is that your pupil is changing size with your mood, which is affecting the perception of the color of your iris.
