OTF: Colour Font, COLR Layers over CFF Outlines

COLR and CPAL over CFF rather than glyf outlines. COLR is outline-agnostic by specification, but plenty of tooling assumes colour fonts are TrueType-flavoured: this is the file that finds out. Original typeface, free to use.

Testing contract

Expected to pass
Scenario
Load the OTF and render the icon codepoints in a COLR-aware renderer.
Expected result
Colour layers render from CFF charstrings; the table directory shows CFF with no glyf, and the fallback path still draws monochrome outlines.

What is a .otf file?

OTF (OpenType Font) is a scalable font format built on the TrueType structure but able to carry PostScript/CFF cubic-Bezier outlines and advanced typographic features like ligatures and alternates. It supports large Unicode glyph sets and rich layout tables. It is a professional-grade format for desktop and web.

How to use this file

Use an example OTF to test OpenType parsing, advanced layout-feature handling, glyph extraction, and font-conversion or subsetting pipelines.

How to use this file for testing

“OTF: Colour Font, COLR Layers over CFF Outlines” is a deterministic Testaroo fixture for Conversion testing, Web assets. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.

Documented properties for this file: seed 20260807. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.

Font fixtures carry a small documented glyph set across the common wrappers. Test font loaders, subsetting, and @font-face; the specimen preview renders the glyphs the face actually maps.

Code examples
