UX Intelligence Tip
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 to Use Principles of Accessible Chroma
- 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.
