A muted, desaturated green that sits closer to grey than a vivid green does — green enough that 'grey' alone would be wrong, and quiet enough that 'green' alone overstates it. Frequently described as the colour that looks green outdoors and grey indoors, which is a fair description of how little saturation it carries.
greyer end
An illustrative approximation only — a flat swatch cannot reproduce the depth and scattering of a real iris.

A cool, low-saturation green with little warmth; some show a faint blue cast.
How much green is present relative to grey, and whether any warm flecking appears near the pupil.
Shifts markedly between daylight and artificial light, and is strongly influenced by clothing colour worn near the face — a green top can make the green component obvious where a grey one suppresses it.
Particularly unreliable in photographs. Automatic white balance alone can move the recorded colour from convincingly green to convincingly grey without anything about the eye changing.
Grey-green is a common everyday description, but it is not a category population studies count separately from grey or green, so no reliable prevalence figure exists for it.
No separate prevalence figure exists, because no study counts grey-green as its own group. A number presented as one would reflect where a particular study drew its boundary rather than how often the appearance occurs. None is stated here.
Styling ideas below are optional and editorial — never rules, and never a claim that one colour choice is objectively correct for anyone.
Confidence: low. Geographic scope: Not tracked as a separate category in the available literature, so no geographic distribution can be stated for it.
