I can totally understand why some people might like to see hazel eyes on Dorian. But, have hazel eyes really been that uncommon in companions?
Alistair (in game) - hazel
Morrigan - pale brown/amber
Leliana - blue
Wynne - blue
Zevran - hazel
Oghren - blue
Loghain - blue
Sten - violet
Anders - brown
Nathaniel - blue
Sigrun - blue
Velanna - blue
Carver - blue
Bethany - brown
Aveline - green
Varric - hazel
Fenris - hazel
Merrill - hazel
Sebastian - blue
So, if we are totaling up the eye color of the companions (minus non-humanoids), we have:
9 blue, 5 hazel, 2 brown, 1 green, 1 amber, 1 violet
Yeah, blue eyes are over represented, but hazel is pretty high too.
I loved the concept and fan art of Dorian with dark skin and striking light eyes. I was a little disappointed when his eyes were hazel since I felt like most of the male love interests (Alistair, Zevran, Fenris, Anders) had some form of brown or hazel eyes. Only Sebastian has blue eyes. So I'm kind of happy for the change. I think his eyes look amazing in that shot and it's actually added a little more fuel for the fire. I love light eyes like that.
That being said, I do understand people who would like to see brown guys represented who also have brown eyes. I can understand the concerns about 'white-washing'. I think it's kind of interesting (and possibly relevant) to note that Dorian was actually much lighter in the earlier concept art and got darker as the process came along. Of course, we have no idea what his eye color was at that point.
