Solas's eyes turn up grey-blue in my game, though that might be due to the HD eye texture mod. And the wolf's eyes on the Heirophant card are blue, as I recall.
They're actually yellow-ish:
Anyway - living in a nation where a heck of a lot of people have grey eyes (it's like when you go to Scandinavian countries and many people there have blue eyes and blond hair, over here a lot of us have gray eyes and mousy blond or brownish hair) I concede that sometimes it may be hard to identify the color, since it can vary depending on lighting conditions or what they reflect.
Heck, I myself had problem identifying mine for a few years
(until I figured out it's because I have a gold-ish ring around a pupil. Central heterochromia ftw)
Still, both in my game as well as plethora of screenshots I've seen, including those with clear lighting conditions, they've rarely been anything other than clear gray.
