I have the same situation as you. I have silver gray eyes then turn green. But medically it's whatever your eyes predominantly are.
What Is It Called When Your Eyes Are Only Blue/green With No Hint Of Brown?
It called,..... Teeeaal
I have eyes like that. Everyone tries to say they are green, but they are not. Mine are classified as blue because that was the original color. I just pick up the green. So, whichever color appears the most in your eyes is what you could classify them as.
