Hello. I don't need to explain myself too much. Colour fonts are not only applicable to the web or graphics design, but adding emoji with colour also livens up presentations (working on one on Impress right now) and maybe even informal Writer documents. So it is not out of scope for LibreOffice to support colour fonts. IIUC (as per https://www.colorfonts.wtf/) OpenType-SVG are the "industry standard" for colour fonts. It would be great for LibreOffice to be the first ordinary-user-accessible document production software to support colour fonts!
Created attachment 135604 [details] Usage example Snippet from a presentation using 1F914 THINKING FACE glyph from https://github.com/emojione/emojione/tree/2.2.7/assets/png. With support for OpenType-SVG colour fonts I could just use https://github.com/eosrei/emojione-color-font and not have to fiddle with external PNGs and positioning.
Indeed, that would be nice. The font works with browser SeaMonkey.
