huidtintmodifiers

Huidtintmodifiers, or skin tone modifiers, are a set of Unicode characters that enable emoji depicting people or body parts to appear in different skin tones. The modifiers consist of five code points, U+1F3FB through U+1F3FF, which correspond to the Fitzpatrick skin-tone scale from light to dark. When a base emoji that represents a person or a body part supports skin tone variation is followed by one of these modifiers, the resulting emoji is rendered in the selected tone.

Encoding and usage: The modifiers are appended to a suitable base emoji. For example, a person or hand gesture emoji can be followed by a modifier to indicate a specific skin tone. They are intended to work with emoji sequences that designate a single person or role; some sequences that include gender, family relationships, or professions may use additional characters or zero-width joiners to form a single perceived emoji. Not all base emojis support skin tone modifiers; if a base does not define skin tone, the modifier is typically ignored by the rendering system.

Rendering and compatibility: Implementation varies across platforms and fonts. While most modern systems render the modifier correctly when supported, cross-platform differences can lead to inconsistent appearances. Some platforms may display a neutral default tone for certain emoji, or treat the sequence as separate symbols rather than a combined unit. Accessibility tools generally announce the base emoji followed by the tone, though reporting can differ between assistive technologies.
