How Our Accessibility Tools Support Your Workflow

WCAG Contrast Checking

Calculate contrast against WCAG 2.1 to pick safe foreground/background combinations for text, buttons, and icons to avoid readability issues.

Design‑to‑Code Alignment

Use generated CSS snippets to land accessible palettes in stylesheets or design tokens so design and engineering share the same standard.

Systematic Color Pairs

Save passing foreground/background pairs to build a project-level semantic color system instead of one-off decisions.

Pipeline Integration Ready

In production you can use the same contrast logic in CLI or CI steps to block non-compliant color combinations from shipping.
