Also described as: pale blue eyes, ice blue eyes, sky blue eyes
A pale, clear blue with very little depth, often with a visibly lighter zone around the pupil and a comparatively distinct darker ring at the outer edge. The paleness makes the iris fibre structure unusually easy to see.
typical range
An illustrative approximation only — a flat swatch cannot reproduce the depth and scattering of a real iris.
Consistently cool; some show a faint grey or steel cast rather than a pure blue.
How prominent the limbal ring at the outer edge is, and how much of the pale inner zone shows.
Highly responsive to surroundings. Because the iris carries so little colour of its own, a blue shirt or a warm lamp shifts the apparent result more than it would for a saturated eye colour.
Easily blown out by flash and by bright exposure, which removes the fibre detail that makes this category recognisable and can render it as an almost featureless pale disc.
Blue eyes are reported with notably higher prevalence in Northern and Eastern Europe than in most other studied world regions, though exact figures vary between sources.
Regional boundaries in the underlying literature are not perfectly consistent, and precise percentages vary between individual studies. Presented here as a directional, well-corroborated pattern rather than one exact figure.
Styling ideas below are optional and editorial — never rules, and never a claim that one colour choice is objectively correct for anyone.
Confidence: medium. Geographic scope: Part of the broad blue category, which is reported at markedly higher frequency in northern and eastern European populations.
