This topic might fit better in the "lore" part of the forum, since it's not so much a game mechanic. That said; i think it is as varied as human eye colours, perhaps leaning towards the darker colours. I think it's not been set in stone on purpose; if you want to declare as a dm that all the orcs in the setting have brown eyes, then still half-orcs would be a bit different. So I wouldn't pay too much attention to it and just choose a colour that fits for your character :)
This is surprisingly rarely talked about. Human eye color is obvious, but I have struggled to find information regarding orc (and half-orc) eye color.
