Welsh skin tone: Fitzpatrick type and undertone in 60 observed portraits
Welsh: fitzpatrick skin type Range II-III in 52% of 60; skin undertone Warm (yellow / golden) in 56% of 43; pigmentation pattern Uniform in 91% of 64; freckling density None in 80% of 70.
Catalog portraits for Welsh are AI-generated adult subjects; the measurements on this page come from documented photographs of real people, not from these images.
Fitzpatrick skin type
n = 60 assessable · 11 not assessableSix-class ordinal classification of constitutive skin pigmentation, originally developed for sun-reactivity assessment but now the de-facto skin-tone vocabulary in dermatology and computer-vision fairness research.
| Value | Share | n | |
|---|---|---|---|
| Type I — very fairAlways burns, never tans. Pale white skin, often with red or blonde hair, blue/green eyes, freckles. Common in Northern European populations of Celtic / Scandinavian descent. | 2% | 1 | |
| Type II — fairBurns easily, tans minimally. Fair skin, light hair, light eyes. Common in Northern European populations. | 37% | 22 | |
| Type III — mediumSometimes burns, gradually tans. Light olive to medium skin tone. Common in Mediterranean European, Middle Eastern, and East Asian populations. | 7% | 4 | |
| Type V — brownRarely burns, tans deeply. Brown skin tone. Common in South Asian, North African, Middle Eastern, some Latin American populations. | 2% | 1 | |
| Range II-IIIBridging type used when assessment indicates the subject sits between Types II and III. Acceptable per the original Fitzpatrick description. | 52% | 31 | |
| Range III-IVBridging type used when assessment indicates the subject sits between Types III and IV. | 2% | 1 |
Vocabulary: Fitzpatrick skin type (fitzpatrick_1988)
Skin undertone
n = 43 assessable · 28 not assessableHue character of the skin independent of overall depth (Fitzpatrick). Reflects relative balance of hemoglobin (red), melanin (brown), and carotenoid (yellow) contributions to perceived color.
| Value | Share | n | |
|---|---|---|---|
| Warm (yellow / golden)Yellow, peach, or golden cast. Veins on inner wrist appear greenish. | 56% | 24 | |
| Cool (pink / red / blue)Pink, rosy, or bluish cast. Veins on inner wrist appear blue or purple. | 35% | 15 | |
| NeutralBalanced; neither warm nor cool dominant. | 9% | 4 |
Vocabulary: Skin undertone (undertone_qualitative)
Pigmentation pattern
n = 64 assessable · 7 not assessableDistribution pattern of skin pigmentation independent of overall Fitzpatrick depth.
| Value | Share | n | |
|---|---|---|---|
| UniformEven pigmentation across visible skin; no obvious lighter or darker patches. | 91% | 58 | |
| LentiginesLarger, persistent macules independent of sun exposure. Common with photoaging; can also be constitutional. | 8% | 5 | |
| Freckled (ephelides)Visible ephelides — small, well-circumscribed, sun-induced macules. Concentrated on sun-exposed areas; common in Fitzpatrick I-III. | 2% | 1 |
Vocabulary: Pigmentation pattern (pigmentation_pattern_qualitative)
Freckling density
n = 70 assessableDensity of visible freckles (ephelides) on the face. A separate dimension from pigmentation_pattern because freckling density varies continuously and is meaningful even within the freckled category.
| Value | Share | n | |
|---|---|---|---|
| NoneNo discernible freckles. | 80% | 56 | |
| FewSparse freckles, scattered, easy to count individually. | 19% | 13 | |
| ModerateClearly freckled but countable in clusters. | 1% | 1 |

Where these numbers come from
71 publicly documented portraits of notable Welsh people were assessed by a vision model against the full 22-vocabulary schema, one value per dimension. 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.
These rows are not yet in the published catalog dataset, which currently carries the earlier single-row analysis; see the methodology. A family page exists only when at least 10 portraits carry an assessable value.
