Eye colours can change, but it is only common in infants, where after the colour will become permanent.  Unless much sunlight exposer is done upon the eyes during adult life, the colours don't change.

And they certainly do not change on mood.  Mood changing eye colour makes no sense, not even biologically, the brain does not inform its eyes what mood it is in, in fact, I don't think the brain informs any part of your body what mood it is in.

Instead, it tells "you", and you just manipulate with your facial expressions.  But you cannot change your eye colour.  It's a myth, you are just seeing in the mirror what you want to see.
