RandomA11y for accessible color combinations
Tool powered by . Uwarp embeds the original tool; terms and exports are defined on the publisher site.
Browse RandomA11y for WCAG contrast-safe pairs and accessible color combinations. Generate random foreground and background sets.
What is RandomA11y?
RandomA11y at https://randoma11y.com/ is an accessible color combination explorer: it surfaces foreground and background pairs filtered for common WCAG color contrast expectations so you can browse or generate random sets without hand-calculating every ratio. Teams use it for accessible palette inspiration before they map roles in a design system or theme file. This Uwarp page embeds the public app next to /contrast-checker and /accessible-brand-colors so you can shortlist pairs and re-validate in your real UI.
What you can do in the embed
Discovery and handoff for contrast-aware color work on randoma11y.com.

- Copy values into your stack: Paste hex or other outputs from the live site into Figma variables or CSS when exposed.
- Seed light and dark themes: Use pairs as starting points before you expand into full semantic token sets.
- Pair with dedicated checkers: Follow up on /contrast-checker for final QA on the type sizes and weights you ship.
How to use RandomA11y on Uwarp
Treat suggestions as a first pass, then validate in product context.
- Match real text styles: Compare candidates at the font size and weight you use in production, not only defaults.
- Test worst-case backgrounds: Re-check pairs on images, gradients, or tinted surfaces where contrast can drop.
- Name semantic tokens: Map accepted colors to roles like text.primary and surface.default before handoff.
- Regression-test after tweaks: Small hue shifts can break related pairs—retest critical screens when themes change.
Tips for accessible color in UI
Contrast ratios help; perceived readability and brand tone still need review.
- Check non-text elements: Icons, borders, and focus rings may need separate WCAG graphics checks.
- Balance brand and accessibility: A passing pair can still feel off-brand—adjust saturation while keeping ratio targets.
- Document AA vs AAA goals: Note which text styles require which level so future edits stay intentional.
- Respect system settings: Forced-colors and high-contrast modes can change how pairs render—test on target OS settings.
Who RandomA11y is for
Anyone who needs many contrast-safe options without building spreadsheets from scratch.
- Product and marketing designers: Prototype landing pages where text must stay readable on first review.
- Indie and startup teams: Ship accessible color defaults without a dedicated color specialist.
- Developers theming UIs: Seed themes with pairs more likely to pass automated contrast checks in CI.
- Design system triage: Explore accent hues that still fit WCAG color contrast rules beside existing tokens.
