TTF: Colour Font, COLR v1 Linear and Radial Gradients

A COLR version 1 colour font built as a real paint graph: a linear gradient with pad extend, a radial gradient with reflect, a repeating three-stop gradient, and a solid paint with fractional alpha. For testing gradient support, extend-mode handling, and the v1-to-v0 fallback path. Original typeface, free to use.

Testing contract

Expected to pass
Scenario
Render the three icon codepoints in a COLR v1 renderer, then in a v0-only renderer.
Expected result
The v1 renderer paints gradients with three distinct extend modes and one 65 percent alpha layer; a v0-only renderer falls back to the monochrome glyf outlines rather than failing to load the font.

What is a .ttf file?

TTF (TrueType Font) is a scalable outline font format developed by Apple and Microsoft that uses quadratic Bezier curves and includes hinting for sharp rendering at small sizes. It stores glyph outlines, metrics, and character mappings in a single file. It is one of the most widely supported desktop and web font formats.

How to use this file

Use an example TTF to test font parsers, glyph and metric extraction, text-rendering pipelines, and converters that produce web font formats like WOFF.

How to use this file for testing

“TTF: Colour Font, COLR v1 Linear and Radial Gradients” 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

@font-face {
  font-family: "Sample";
  src: url("NovusColorGradients.ttf");
}
body { font-family: "Sample", sans-serif; }
