The Accessibility-Safe Palette is a free, instant online tool for generating a UI palette where text and accent pass WCAG AA against the background. This complete guide walks through what it does, how to use it, where it works best, practical tips, and answers to common questions — everything you need to get great results without any signup or installation.
What is the Accessibility-Safe Palette?
An accessibility-safe palette generator builds a UI color set where the text and accent colors are guaranteed to clear WCAG AA contrast against the background. Starting from a white background, it takes your chosen accent hue and walks each role, heading, body, accent, and muted text, down in lightness until it reaches the 4.5:1 ratio required for normal text, reporting the achieved ratio beside each color so you can verify compliance at a glance. This removes the trial-and-error of picking a brand-tinted text color only to discover it fails an audit. The relative luminance and contrast math run inline using the official WCAG formula, so the numbers are real. Designers and developers use it to seed a compliant theme, choose readable on-white text tones, or prove accessibility in a review. Each value is a labelled, paste-ready hex code annotated with its contrast ratio against the background.
How to use the Accessibility-Safe Palette
Getting a result takes only a few seconds:
- Set your accent hue from 0 to 360.
- Click Generate to build the compliant palette.
- Read the contrast ratio beside each color.
- Apply the text and accent tones on a white background.
You can open the Accessibility-Safe Palette and start generating right away. Because it runs instantly and for free, it costs nothing to generate several times and keep the result that fits best.
Common use cases
The Accessibility-Safe Palette suits a range of situations:
- Seeding a WCAG-compliant theme on a white background
- Choosing on-white text tones that pass AA
- Picking an accent that meets text contrast
- Documenting contrast ratios for an audit
- Avoiding brand colors that fail accessibility
Across all of these, the appeal is the same: a fast, repeatable result that would take far longer to put together by hand, available the moment you need it.
Tips for better results
- Keep body text at 4.5:1 or higher for AA.
- Use the reported ratios as audit evidence.
- Large text can pass at the lower 3:1 threshold.
- Re-check colors if you change the background.
Frequently asked questions
How does it guarantee AA
For each role it steps the color darker in lightness while measuring the real WCAG contrast against the white background, stopping once the ratio reaches 4.5:1, the AA threshold for normal text. The achieved ratio is shown beside each hex.
Why is the background white
White is the most common UI background and the toughest to pass colored text against. Anchoring on white means the derived text and accent tones are conservative and will usually pass on lighter tinted backgrounds too.
Does AA cover everything
AA 4.5:1 covers normal body text; large text passes at 3:1 and AAA wants 7:1. For non-text UI like borders and icons, the requirement is 3:1, so check those separately against their neighbours.

Why use a accessibility-safe palette?
The appeal of a accessibility-safe palette is speed. It gives you ready-to-use color values in seconds, turning a task that would otherwise mean a blank page or manual effort into a quick, repeatable step you can run whenever you need it. It runs entirely in your browser, costs nothing, and never asks you to sign up, so you can generate again and again until a result fits — then take it into your own work and refine it from there. Because there is no cap on how many times you run it, the smart approach is to generate several options, compare them side by side, and keep the one that lands rather than settling for your first attempt.
