What color eyes does declan galbraith have?

Answer 1

They've three colours; around the iris is pure brown, but around that there's a lot of green and also remarkable amount of pure blue. Most of the time his eyes appear brown, but in some lights green - changing between those two colours. The blue, though a lot and very pure in close look, never seems to affect his "main" eye colour. Thus, I think the simpliest answer would be; he has hazel eyes.

Answer 2

They've three colours; strong brown circle around the iris, then pale green for the most parts but also a remarkable stripe of strong and clear blue. Usually his eyes look just brown or just green, so I guess the most common definition would be hazel.
