The Fitzpatrick Scale in Your Keyboard
Before 2015, every human emojiEmoji

Emoji 1.0 changed that by introducing five skin tone modifiers based on the Fitzpatrick dermatological scale, a classification system developed by Thomas B. Fitzpatrick in 1975 to describe skin's response to UV light.
The five modifiers map to Fitzpatrick types I-VI:
| Modifier | Code Point | Fitzpatrick Type | Example |
|---|---|---|---|
| 🏻 | U+1F3FB | Type I-II (Light) | 👋🏻 |
| 🏼 | U+1F3FC | Type III (Medium-Light) | 👋🏼 |
| 🏽 | U+1F3FD | Type IV (Medium) | 👋🏽 |
| 🏾 | U+1F3FE | Type V (Medium-Dark) | 👋🏾 |
| 🏿 | U+1F3FF | Type VI (Dark) | 👋🏿 |
The default yellow (no modifier) serves as a generic, non-realistic skin tone.
How They Work Technically

👍 (U+1F44D) + 🏽 (U+1F3FD) = 👍🏽
Not all emoji support skin tones. Only emoji depicting human body parts or people can be modified. Abstract emoji (💀 skull, 👻 ghost) and non-human characters don't accept modifiers.
When a modifier follows an emoji that doesn't support it, the modifier is shown separately as a colored square — a visual cue that the combination isn't valid.
Multi-Person Skin Tones
One of the more complex aspects of skin tone modifiers is how they work with multi-person emoji. Starting with Emoji 12.1 (2019), handshake and couple emoji support different skin tones per person:
🫱🏻🫲🏿 = Light hand + ZWJ + Dark hand
This required new ZWJ sequences because each person in the emoji can have an independent skin tone. The combinations multiply quickly — two-person emoji with 5 skin tone options each create 25 possible combinations.
The Impact
Skin tone modifiers were one of the most significant additions to the emoji standard. They acknowledged that a universal communication system should represent the diversity of its users.
Usage data shows interesting patterns: - The default yellow remains the most commonly used across all human emoji - Skin tone usage varies significantly by region and demographic - Many users consistently use one skin tone across all modified emoji - Professional/workplace contexts tend to use the default yellow more often
Platform Differences
Different platforms render skin tones with slightly different color values:
- Apple uses warm, naturalistic tones
- Google tends toward slightly more saturated tones
- Samsung has historically used different hue ranges
- Microsoft uses tones consistent with their Fluent design system
These differences are subtle but real — the same skin tone modifier can look noticeably different across platforms.
