Funny eyes

Léon has a strange mix of blue, green, yellow and grey in his eyes. It is often hard to put your finger on what colour they are, and they simply often reflect his clothing... he has blue eyes when he is wearing a blue t-shirt, green, when he's wearing green, so for fun I decided to put a photo of him through the photoshop filter that removes all except a specific colour from a photo - I chose blue. Interestingly, it seems the bottom half of his eyes are predominantly blue, but the top two halves have come out in grey so they must be green or grey!
