Standards & Specifications

Our technical content relies on these primary sources:

  • W3C — CSS Color Module Level 4 (w3.org/TR/css-color-4)
  • W3C — Web Content Accessibility Guidelines (WCAG) 2.2 (w3.org/TR/WCAG22)
  • WHATWG — HTML Living Standard (html.spec.whatwg.org)
  • ECMA International — ECMAScript Language Specification
  • CIE — Commission Internationale de l'Éclairage colorimetry standards

Where our technical claims rely on these specifications, we cite them inline. Color formulas, contrast ratios and accessibility thresholds are all sourced from these primary documents.

Foundational Color Theory Books

Our explanatory content on color theory references these foundational works:

  • Josef Albers — Interaction of Color (Yale University Press, 1963; revised 2013)
  • Johannes Itten — The Art of Color / The Elements of Color (1961)
  • Betty Edwards — Color: A Course in Mastering the Art of Mixing Colors (2004)
  • Albert Munsell — A Color Notation (1905)

These are standard references in every color theory curriculum. We do not reproduce their text; we reference their concepts with attribution.

Color Science Research

Our color blindness simulator and perception-related content draw on:

  • Brettel, H., Viénot, F., & Mollon, J.D. — "Computerized simulation of color appearance for dichromats" (Journal of the Optical Society of America A, 1997)
  • Viénot, F., Brettel, H., & Mollon, J.D. — "Digital video colourmaps for checking the legibility of displays by dichromats" (Color Research & Application, 1999)
  • Machado, G.M., Oliveira, M.M., & Fernandes, L.A.F. — "A Physiologically-based Model for Simulation of Color Vision Deficiency" (IEEE TVCG, 2009)

These are the standard academic references for CVD simulation and are used by every professional design tool.

Framework Color Palettes

Our framework color references draw directly from these open-source projects:

Color values are referenced; framework code is not used on OmniColor.

Web Platform References

Technical articles on CSS, JavaScript and browser APIs reference:

Design System Documentation

Our articles on design systems reference:

  • Material Design — Google's design language documentation
  • Human Interface Guidelines — Apple's design system
  • U.S. Web Design System (USWDS) — U.S. Government design system
  • Radix Colors — Radix UI's accessible color system
  • Tailwind CSS documentation — Tailwind Labs

Research Papers and Articles

When we cite specific research on color perception, accessibility or design, we link to primary sources — typically peer-reviewed papers, conference proceedings or published specifications. We do not cite secondary coverage as if it were primary.

Data Sources

Any statistics on OmniColor — for example, "1 in 12 men have color blindness" — are sourced from credible published research. We do not invent statistics and we cite our sources inline.

Third-Party Quotes

When we quote a person or publication, we:

  • Quote only brief excerpts (fair use)
  • Attribute clearly to the original source
  • Link to the source when publicly available
  • Do not alter the meaning of quotes
  • Do not use quotes from sources that cannot be verified

Contributors Cited

Some of our articles have been written by or with input from guest contributors. Their attribution appears on the article itself. See our Editorial Team page for our collective expertise.
