There blue! But I have found they can change colour quite frequently to green, but they are mostly blue, so you could say they are greeny-blue or bluey-green!
Yeah Sheamus eyes are blue but they can change their colour it's the same with me, my eyes are blue but they change to green when it's sunny, to grey when it's cloudy and to blue when it's raining so you can't say he only have one colour because he has these three colours i've seen it in photos...
