The Fitzpatrick Scale in Your Keyboard
Before 2015, every human emoji had the same yellow skin. 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
A skin tone modifier is simply appended after a base emoji character. No ZWJज़ीरो विड्थ जॉइनर (ZWJ)
एक अदृश्य Unicode वर्ण (U+200D) जिसका उपयोग कई इमोजी को एक संयुक्त इमोजी में जोड़ने के लिए किया जाता है, जैसे लोगों और वस्तुओं को पेशे वाले इमोजी में संयोजित करना। needed — the modifier directly follows the base:
👍 (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.
