Catalans eyes: iris color, shape and epicanthic fold in 23 observed portraits
Catalans: iris color dark brown in 57% of 23; epicanthic fold absent in 100% of 40; eye shape deep-set in 47% of 38.
Catalog portraits for Catalans are AI-generated adult subjects; the measurements on this page come from documented photographs of real people, not from these images.
Iris color
n = 23 assessable · 25 not assessablePredominant color of the iris. Heterochromia is captured as its own value; mixed colors (e.g. hazel, blue-green) get distinct buckets.
| Value | Share | n | |
|---|---|---|---|
| dark brownIris appears nearly black under typical lighting; high melanin content. Common in East Asian, South Asian, Sub-Saharan African, and indigenous populations. | 57% | 13 | |
| hazelMixed brown and green/gold; central iris differs in color from peripheral iris (central heterochromia). | 13% | 3 | |
| blueTrue blue; highest frequency in Northern European populations, decreases southward. | 30% | 7 |
Vocabulary: Iris color (iris_color_qualitative)
Epicanthic fold
n = 40 assessable · 8 not assessablePresence and morphology of the epicanthic fold — the skin fold of the upper eyelid that may cover the medial canthus. Significant ethnic variation; high prevalence in East Asian, Central Asian, and indigenous American populations.
| Value | Share | n | |
|---|---|---|---|
| absentNo epicanthic fold; medial canthus clearly visible. | 100% | 40 |
Vocabulary: Epicanthic fold (duke_elder_epicanthus_classification)
Eye shape
n = 38 assessable · 10 not assessableOverall shape of the visible eye, considering the silhouette of the upper and lower lid margins together. Independent dimension from eyelid_crease_type and epicanthic_fold, which capture finer morphological variation.
| Value | Share | n | |
|---|---|---|---|
| deep-setEye sits deep within the orbital socket; pronounced shadow above the upper lid. Brow ridge typically prominent. | 47% | 18 | |
| almondSlightly elongated horizontal axis; mild taper at lateral and medial canthi. Considered the aesthetic reference shape. | 39% | 15 | |
| hoodedUpper lid skin descends over the lid crease, partially or fully covering the upper lid platform. Often associated with periorbital aging but can be constitutional. | 13% | 5 |

Where these numbers come from
48 publicly documented portraits of notable Catalans people were assessed by a vision model against the catalog vocabulary, one row per portrait. Values are what the photographs show, read by a model, not population measurements. Each table counts only portraits where the value could be assessed; covered, obscured and unclear portraits are reported separately.
Notable-people corpora skew older, so hair color over-represents gray and white, and image quality varies. Treat shares as a description of this sample. Mean model confidence for this family: 0.54. 25% of portraits are high quality.
The same rows are published as image_observations in the catalog dataset; see the methodology. A family page exists only when at least 10 portraits carry an assessable value.
