Is this the official RandomA11y website?

The iframe points to the public app at https://randoma11y.com/, the RandomA11y project domain.

Does using RandomA11y replace a full accessibility test?

No. It helps with color and contrast selection. You still need to test components, focus states, motion, and assistive technology behavior in your real product.

Why do some pairs look different in my app than on the site?

Font rasterization, subpixel settings, and background images can change perceived contrast. Re-check in the actual interface and on target devices.

Can I use the colors in commercial projects?

The colors you pick are not “owned” by the tool, but you should read any terms, attribution, or license notes published on randoma11y.com for the service itself and for copied code.

RandomA11y for contrast-safe color inspiration

Open RandomA11y on randoma11y.com: browse and generate accessible foreground and background color combinations for interfaces; use the live app for current contrast rules, copy, and any export options.

What is RandomA11y?

RandomA11y is a web app that surfaces color combinations—typically text and background pairs—selected so they meet common accessibility contrast expectations for digital interfaces. It is useful when you need fresh, usable pairs without hand-tuning every hex value, and when you want a starting point before you move choices into a design system or code theme. The project describes itself as a large, browsable set of such combos on randoma11y.com. This Uwarp page embeds the public site at https://randoma11y.com/ so you can explore next to your other contrast and palette tools. Always confirm final ratios in the environments you ship, because real type weight, size, and anti-aliasing can still change perception.

What you can use RandomA11y for

The tool supports discovery and handoff, not a full accessibility audit on its own.

Find pairs that pass common contrast bars: Move past guesswork for body and large text by starting from combinations already filtered for contrast.
Inspire new brand directions: Use random or browsable combinations as a mood board step before you lock broader palettes.
Copy values into your stack: Paste hex or other outputs from the site into Figma variables or CSS when the app exposes them.
Pair with your existing tokens: Check whether a suggested pair can sit beside your primary and surface roles without clashing.

How to use this embedded app

Treat suggestions as a first pass, then validate in product context.

Pick a real text style: Compare candidates at the size and weight you ship, not only at default browser sizes.
Test light and dark regions: If the pair will appear on images or gradients, re-check contrast on the worst case frame.
Name tokens when you promote a pair: Map accepted colors to semantic roles so engineering does not hardcode ad hoc values.
Re-run checks after theme tweaks: Small shifts to one token can break another pair; regression-test critical screens.

Tips for accessible color in UI

Contrast ratios are one input; perceived readability still needs review.

Do not skip non-text elements: Icons, borders, and focus rings may need their own pair checks under WCAG graphics guidance.
Watch brand saturation: A valid pair can still feel off-brand; balance accessibility with the tone your team expects.
Document the ratio you targeted: Note whether the team aims for AA or AAA for a given text style so future edits stay intentional.
Combine with user settings: Respect system contrast and forced-colors modes; no single pair covers every user configuration.

Who this tool works well for

Anyone who needs many contrast-safe options without building a spreadsheet from scratch.

Product and marketing designers: Prototype landing pages and in-app screens where text must stay readable on first review.
Indie and startup teams: Ship accessible defaults quickly when you do not have a dedicated color scientist on call.
Developers theming UIs: Seed light and dark themes with pairs that are more likely to pass automated checks in CI.
Design system triage: Explore adjacent hues when an existing token set needs a new accent that still fits contrast rules.

Benefits of using RandomA11y in Uwarp

Embedding the explorer keeps accessible inspiration next to the rest of your color tools.

Faster than manual contrast math for ideation: You iterate on feel while the first-pass math is already in range.
Consistent with other Uwarp checkers: Jump to dedicated contrast or palette tools on this site when you need deeper controls.
Single tab for quick reviews: Stakeholders can open the embed during a call instead of each cloning a private file.
No modification of the upstream tool: Uwarp does not change RandomA11y; behavior and data stay defined on randoma11y.com.
