I have greeny brown eyes - hazel but mostly green. When tired or headachy they are more green than brown, but at night, more brown than green.
A friend once described her blue eyes as Sparkling Blue Ocean, and mine, as Pond Scum Green. Not very nice really, she said it to show off to the boy she liked - but it does actually fit how they look. And I dont mind. At least Pond Scum has character :)
