Accessibility Statement

Short answer

We aim for accessible content and controls, but visual color tests require sight and some arrangement tools have limited keyboard support. The known limitations and feedback contact are below.

Our target

Color Vision Labs aims to conform to the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA across the whole site. Accessibility review is part of how we build: new pages and components are checked against the measures below before they ship.

Measures in place

  • Semantic HTML with landmark regions, and a skip-to-content link on every page
  • All interactive controls reachable and operable by keyboard, with visible focus states
  • Text and interface colors meet WCAG AA contrast ratios
  • Images carry text alternatives; decorative graphics are hidden from assistive technology; test plates rendered to canvas expose role="img" with a descriptive label
  • Animations respect the prefers-reduced-motion setting
  • No accounts, no cookies requiring consent, no tracking walls — content is directly reachable
  • Camera frames and photos in the filter tool are processed on-device and never uploaded

Known limitations

Color vision tests are inherently visual

Screening plates, hue-arrangement tests, and the anomaloscope demonstration ask the eye to distinguish colors — that task cannot be conveyed through a screen reader. The surrounding explanations, instructions, and results are readable with assistive technology, but the tests themselves require sight. This is a limit of the subject matter, not an oversight we can engineer away.

Drag-based tests have limited keyboard support

The Farnsworth D-15 and FM-100 hue tests use drag-and-drop cap arrangement. Keyboard-only operation of these two tools is currently limited; improving it is on our roadmap. The plate-based tests (Ishihara-style, HRR, kids' tests) are fully keyboard-operable.

For designers and developers

If you're checking your own work for color accessibility, our color blindness simulator shows any image — a chart, a screenshot, your own upload — as a person with protan, deutan, or tritan vision sees it, at any severity, without the image leaving your browser. It's the fastest way to find color pairs that fail color-blind viewers.

Feedback

If you hit an accessibility barrier anywhere on this site, we want to know. Email support@colorvisionlabs.com and we'll respond as soon as we can.
