Why my eyes change color with my atitude?

Question

When I'm happy I have blue eyes, I have green eyes when just feel good or grey most of the time. I also noticed that these colors sometimes blend in eachother or combine like a very simple caleydoscope. I have myopia(nearsight) and sometimes can see nothing especially in the dark or I can see pretty clear. I use the computer a lot and wear glasses in class. My grandma(motherside) has green eyes the other one has blue eyes. Mom has grey or blue eyes(a bit darker blonde hair) and dad has blue eyes(light brown hair).

Answer 1

my eyes also reflect on the color clothes I wear
