Hei doesn't have blue eyes. His eyes are black.

I had received a new review for one of my many fan-fictions of Darker than Black, and I had the reviewer state that Hei has black eyes, not blue. As many times I have watched DTB (which has been a lot), I know for a fact his eyes are blue.

Dude, go look at some pictures of Hei. He has blue eyes.

I find it kind of funny. How many times had he said that to other fan-fiction authors that wrote Hei has blue eyes.
