He is not blond/blue, he is gray/gray.
Most people who claim blue iris pigmentation actually have gray eyes.
Oh, and stop sucking in your gut and get over your midddle-aged ass.
That's a sign that there's no pigment excreted onto his lens on the front or back, or on the Iris in or around any of its various levels.
I used to have GREEN GREEN eyes ~ and then had surgery that removed a lifelong pigment build up ~ and that turned my eyes BLUE BLUE just like that. They are only slowly returning to the correct color. Frankly, I can hardly recognize myself in the mirror anymore.
