I've been told that my eye colour changes with my mood - I guess this may affect blood-flow within the eye, which may alter refraction capacities, and hence get a change in colour. Is this possible? Does the colour of light entering the eye also affect their colour?

That is indeed a good question! Me does not know the answer..LOL

i don't know the answer, but my ex had green eyes... unless he was mad. then they were grey. and if he wore a blue shirt his eyes were blue...

 I have seen similar.. My husbands eyes do that although I have never noticed a mood difference but it is possible as I wasn't looking for one.

  I will look the next time he comes over and gets angry!!! LOL  Hold still Robert let me look into your eyes and see if the color changes while your angry with me! LOL LOL...OH That would really make him mad then! >>>Yikes..

[kdlynn]

Just bringing this back in.......

Some glaucoma medications have a side effect that Increases the colouring of the iris. But i don't know if your "mood" can change the colour.

Violet eyes are due to a blue iris and red blood vessels,
so vasodilation could change the colour of a violet eye.
Emotions can cause vasodilation, e.g. blushing, anger.

But only in violet eyes?
