PEP, the first colour font in the Colophon library, was released in 2019 as part of a collaboration with designer Dries Wiewauters.
Colour fonts are a relatively new technology, where additional data is embedded into the font file allowing for colour specification, including setting multiple colours within a single glyph.
Support for colour fonts has increased with the development of the industry standard OpenType-SVG format. However, it is still a relatively new format and there are certain limitations to the technology. The below list shows the current applications that support colour font technology:

You may encounter the following issues when using OpenType-SVG colour fonts in Illustrator or InDesign:
— Glyphs may appear in the wrong positions after export to PDF or SVG.
— When applying the Sheer, Rotate, or Reflect effects on colour SVG fonts, the effects
may be lost or the characters may move away from their original positions when the glyph outlines are created.
— When setting text vertically, the character positions may change once exported.
— Character placement may be incorrect when setting text on a spiral path placement.
The software teams are working on fixes to these issues.
