Case study 01 / Accessibility
Accessible color systems that communicate beyond the palette
A practical method for building brand and interface palettes whose text, controls, charts, and status states remain understandable when color perception differs.
The delivery question
How can a visual system stay distinctive without using color as its only signal?
A reliable answer has to connect user needs, implementation constraints, and observable acceptance checks. The following practice keeps those decisions visible from discovery through handoff.
Delivery method
From guidance to a testable implementation.
Each layer answers a different question: what the standards require, how the team will build it, and what evidence will show that it works.
Interpret the guidance
- Define text and non-text contrast targets before selecting final production colors.
- Pair status colors with labels, icons, shapes, or patterns so meaning survives grayscale and color-vision differences.
- Document foreground, background, interactive, disabled, and focus-state combinations instead of approving colors in isolation.
Build the practice
- Create semantic tokens such as text-muted, action-primary, status-warning, and focus-ring rather than naming tokens only by hue.
- Generate a contrast matrix for every approved pairing and prevent unapproved combinations in components.
- Test campaign graphics, UI controls, charts, and exported media under common color-vision simulations.
Validate the result
- Automated contrast checks pass for intended text and component states.
- Errors, warnings, selection, and progress remain identifiable when color is removed.
- Keyboard focus is visible against every supported surface.
