As for human eyes, there's the usual mix of blue, green and brown, but I'm sure if you zoom in you can see some different hues.
EDIT: Just looking through those, we can see Khajiit have black pupils but yellow, orange or blue irises; Argonians have pale green or yellow irises; Dunmers eyes are red or pinkish; Bosmer's eyes can be so dark that they're practically black; Orcs have a wide variety of eye colour, from blue to grey to red to black.
In short, yes. There's lots of variety.
