My late father had same color..smokey grey

Grey.

desaturated blue.

The one on the right (our right) looks bluer. The left one appears more gray.

But regardless of the color, I would wonder why my pupils are different sizes.

They look bluish to me, but they were basically grey when I checked in Inkscape’s colour picker.

The left eye (from the viewer) is a bit darker probably because it’s in more shade.

Blue.

Grey.

The left eye is greenish gray, and the right one is bluish gray.

I think I’ll take another look after I get a full hit of sleep, and my senses have returned to Earth. ;-p
