Methodology — Trait Taxonomy & Phenotype Reference

Performer profiles on LatinaCastings categorize traits using a controlled phenotype vocabulary aligned with the Ethnic Erotic atlas — a 22-category anatomical framework grounded in peer-reviewed dermatological, anthropometric, and trichological scales.

Why a controlled vocabulary

Free-text trait descriptions ("brunette, curvy, light skin") collapse meaningful distinctions and produce inconsistent AI generation results. A controlled vocabulary breaks each trait into discrete dimensions with named buckets — so two profiles that say "Type 2A hair, honey undertone, Fitzpatrick III" are describing the same thing in the same language.

The vocabulary used here is the same one published by the Ethnic Erotic phenotype atlas, which maintains 196 distinct trait dimensions across 853 named buckets, with citations to the underlying peer-reviewed scales for every measurement.

The 22 categories

The full taxonomy spans 22 anatomical categories. The most visible six on a casting profile:

  • Skin

    Fitzpatrick I–VI scale, undertone, pigmentation distribution

  • Head hair

    Color, Andre Walker texture (Type 1–4), hairline pattern

  • Eyes

    Color, shape, eyelid type, epicanthic fold presence

  • Body shape

    Heath-Carter somatotype, waist-to-hip ratio, skeletal frame

  • Nose

    Bridge profile, tip shape, nostril form, alar width

  • Lips & mouth

    Volume, Cupid's bow definition, philtrum length

The remaining 16 categories cover ears, brows, jawline, dentition, neck, shoulders, arms, hands, torso, back, hips, legs, feet, body hair, intimate anatomy, and skin markings (moles, freckles, tattoos). Of the 196 dimensions, 167 are observable from photographs.

Named scales referenced

Where a published scale exists for a trait, the taxonomy uses it directly rather than inventing new categories:

Fitzpatrick I–VI
Skin phototype
Andre Walker Type 1–4
Hair texture
Heath-Carter
Body somatotype
Manning 2D:4D
Digit ratio
Hamilton-Norwood / Ludwig
Hair pattern
Mendieta
Gluteal shape classification

Limitations

  • The vocabulary describes observable traits; it is not a claim about underlying genetics or population statistics.
  • Coverage varies by category. Some dimensions (e.g. exact gluteal shape) require body photographs to score; for profiles with headshots only, those fields are left unset rather than guessed.
  • AI-generated performers are fictional personas — they do not represent specific real people, and trait values reflect the prompt that produced the image, not measurements of a person.
