Is this a blue, gray-blue, or gray eye?

Yes

The only eye colour is brown, anybody without brown eyes is a pigment of someone else’s imagination.

Blue steel

Fun fact! While brown eyes are brown due to pigmentation, blue/green/grey eyes are the colour they are for the same reason the sky is blue: the way the light bends when it passes through a barrier. In both the case of light passing through the atmosphere and light passing through your cornea, blue/green light has just the right wavelength that when the light scatters as it reflects back out, some colours are more visible than others. Depending on the small amount of pigmentation you do have and the lighting conditions you are in, the eye may appear blue, grey-blue or green. All the way grey eyes are more rare and require slightly abnormal corneas. In this particular picture I would say it looks like blue to me.

Hazel. It’s a handy catch-all.

It might be easier to tell if you didn’t use a potato to take the picture.

Hmmm, on my screen with a color filter turned on it looks red.

Definitely has blue in it. Not as bright blue as some. I’d call it blue-grey.
