WCAG 2.2 Color Contrast Matrix & Accessible Palette Studio
Generate comprehensive WCAG 2.2 color contrast matrix grids across your entire design palette directly in your browser. Test every possible background and foreground color combination simultaneously, identifying compliant color pairings for Level AA, Level AAA, and Large Text with zero server uploads.
WCAG 2.2 Color Contrast Matrix & Accessible Palette Studio
Validate accessibility contrast ratios across all brand color permutations in a real-time matrix.
Interactive WCAG 2.2 Color Contrast Matrix & Accessible Palette Studio Workspace
Calculate WCAG 2.1 and 2.2 accessibility contrast ratios across an entire color palette simultaneously. Features real-time permutation matrix, AA/AAA badges, and CSS export.
How This Tool Works (100% Client-Side Engine)
The tool parses an array of hex colors and computes relative luminance for each color using the standard W3C formula. It then executes an NxN matrix calculation computing the contrast ratio (L1 + 0.05) / (L2 + 0.05) for every permutation, rendering an interactive grid with color-coded compliance status badges.
Step-by-Step Guide
Enter Palette Colors
Type or paste your brand hex colors into the palette manager, or select one of the built-in accessible palette presets.
Inspect 2D Contrast Matrix
Review the generated grid showing every foreground and background combination with exact contrast ratios and AA/AAA badges.
Filter & Export Compliant Pairings
Filter the matrix to show only AA-compliant pairings, and copy the approved color combination table to your clipboard.
Why Use This Tool: Privacy & Performance
Building design systems and brand color palettes requires evaluating how each color in the palette interacts with every other color when used as text and background pairings. Testing colors individually in single-pair contrast calculators requires hundreds of manual calculations for an 8-color palette (requiring 56 pairwise checks), making design system auditing tedious and error-prone. ToolByte WCAG Contrast Matrix Studio constructs a complete two-dimensional contrast grid across your entire color palette in real time. The matrix maps all foreground and background permutations into an interactive grid, displaying exact contrast ratios, pass/fail status for WCAG 2.2 Level AA and AAA, and color swatches. Designers and accessibility auditors can instantly identify which color pairings are safe for body text, which are acceptable for large headers, and which must never be paired together.
