Contrast Validator
Ensure your interface is inclusive and readable. Calibrate color pairs against WCAG 2.1 precision standards.
Spectral Legibility
Real-time simulation of your chroma selections. High-precision distribution ensures readability for everyone.
Color alone is insufficient for communication. Deploy icons, textures, or text labels to ensure users with spectral vision variances can successfully navigate your interface logic.
WCAG Engine
Validated against WCAG 2.1 AA and AAA standards to ensure your web architecture remains legally compliant and inclusive.
Live Feedback
Watch the ratio and compliance status update in real-time as you recalibrate colors or type in hex coordinates.
Surface Mockup
Interact with a live UI viewport that follows your palette choices, providing an immediate sense of legibility.

How This Works
Below is everything you need to get from zero to done. No fluff, just the steps and features that matter.
- 1Initialize the 'Foreground Chroma' by selecting a color or typing a HEX code.
- 2Define the 'Background Surface' color to create your testing pair.
- 3Observe the 'Luminance Ratio' - 4.5:1 is the target for standard text (Level AA).
- 4Audit the 'Status Matrix' to see compliance for both standard and oversized text.
- 5Interact with the 'Interface Sample' to visually verify legibility in a real-world context.
- 6Adjust colors iteratively until all compliance checkboxes reach an active state.
- WCAG 2.1 Compliance Logic: Precise luminance calculation for AA and AAA levels.
- Dual-State Validation: Separate testing for normal (body) and large (heading) typography.
- Interactive UI Viewport: High-fidelity simulation of color pairs on a realistic interface component.
- HEX Coordinate Sync: Two-way binding between color pickers and manual hex inputs.
- Accessibility Intelligence: Integrated tips for designing beyond standard color contrast.
Making the Most of It
Good times to reach for this: Grab Principles of Accessible Chroma when a file needs a quick tweak — a conversion, resize, or cleanup — and you don't want to wait for some desktop monster to boot up.
Typical flow:
- Toss your content into the input — text, file, or whatever you're working with.
- Dial in the settings that match what you actually need.
- Glance over the output to confirm it looks right.
- Grab your result: copy, download, or send it along.
Easy traps to avoid:
- Feeding in sloppy input and assuming the tool will magically sort out every edge case — always eyeball the output first.
- Testing with toy data that looks nothing like your real workload, then getting caught off-guard in production.
- Copy-pasting straight into a live project without a ten-second sanity check. That tiny pause saves hours of cleanup.
Your data stays yours: Your files never touch our servers for standard processing. They stay on your device from start to finish.
