OpenType is the dominant font format for modern computing. For emoji specifically, OpenType supports several color font technologies that allow fonts to include full-color emoji glyphs:- **COLR/CPAL**: Layered color vectors (used by Windows, Android/Chrome)
- **CBDT/CBLC**: Embedded color bitmaps (used by Google Noto Color Emoji)
- **SVG in OpenType**: SVG documents embedded in fonts (used by Firefox, Adobe)
- **sbix**: Apple's bitmap format (used by Apple Color Emoji)
Different platforms support different color font technologies, which is part of why emoji look different across devices.
