Kazakhs skin tone: Fitzpatrick type and undertone in 39 observed portraits

Kazakhs: fitzpatrick skin type Range III-IV in 79% of 39; skin undertone Warm (yellow / golden) in 69% of 35; pigmentation pattern Uniform in 93% of 43; freckling density None in 92% of 50.

Catalog portraits for Kazakhs 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 = 39 assessable · 13 not assessable

Six-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.	3%	1
Type III — mediumSometimes burns, gradually tans. Light olive to medium skin tone. Common in Mediterranean European, Middle Eastern, and East Asian populations.	3%	1
Type IV — olive / light brownBurns minimally, tans easily and well. Olive to light brown skin. Common in Mediterranean, Middle Eastern, Latin American, Southeast Asian populations.	8%	3
Range II-IIIBridging type used when assessment indicates the subject sits between Types II and III. Acceptable per the original Fitzpatrick description.	8%	3
Range III-IVBridging type used when assessment indicates the subject sits between Types III and IV.	79%	31

Vocabulary: Fitzpatrick skin type (fitzpatrick_1988)

Skin undertone

n = 35 assessable · 17 not assessable

Hue 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.	69%	24
OliveGreenish-yellow cast; common in Mediterranean, Middle Eastern, and some South / Southeast Asian populations. Often grouped with warm in cosmetic shorthand but anatomically distinct.	20%	7
NeutralBalanced; neither warm nor cool dominant.	9%	3
Cool (pink / red / blue)Pink, rosy, or bluish cast. Veins on inner wrist appear blue or purple.	3%	1

Vocabulary: Skin undertone (undertone_qualitative)

Pigmentation pattern

n = 43 assessable · 9 not assessable

Distribution pattern of skin pigmentation independent of overall Fitzpatrick depth.

Value	Share	n
UniformEven pigmentation across visible skin; no obvious lighter or darker patches.	93%	40
LentiginesLarger, persistent macules independent of sun exposure. Common with photoaging; can also be constitutional.	5%	2
MottledIrregular patches of varying pigmentation without a single named pattern.	2%	1

Vocabulary: Pigmentation pattern (pigmentation_pattern_qualitative)

Freckling density

n = 50 assessable

Density 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.	92%	46
FewSparse freckles, scattered, easy to count individually.	8%	4

Vocabulary: Freckling density (freckle_density_qualitative)

Where these numbers come from

60 publicly documented portraits of notable Kazakhs 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.
