Excuse me ,but for you to tell the person who asked ,if a persons eye color can change and to flat out say that it is not happening with the person they're dating is a bit Audacious .I will have you know that ,yes it can happen .My eyes change to all kinds of colors from light to bright blues ,to shades of dark green,light green ,bright green .Blue green ,green blue ,shades of gray and even Violet .My eye color was a beautiful deep set bright blue ,like the color of the Aquafina water bottle ,when I was born ,then some time later they turned a light green .My eye color changes every day .I have had people tell me that they have actually seen them changing ,where one eye will be green and the other blue .My mom tells me ,when my eyes are different shade of blues or greens ,and a close friend told me they often turn a violet /lavender shade .My Moms eyes do the same thing ,so it's an Inherited Genealogical trait .I have photos to back up my statement and eye witnesses, so for you to tell any one that eyes can not change color was wrong ,because some do .
