Test multiple color combinations for WCAG 2.0 contrast compliance.
About Contrast Grid
What Is Contrast Grid?
Contrast Grid is a free web-based tool in the **Design** category that evaluates color contrast accessibility for web and digital products. Developed by EightShapes, it generates a visual grid to test multiple foreground text colors against background colors, displaying contrast ratios and compliance grades based on WCAG 2.0 standards.
What Contrast Grid Does
- Accepts color inputs in HEX, RGB, HSL, HSLA formats or named colors, with one color per line and optional labels separated by commas.
- Creates a grid matrix showing all combinations of row (background) and column (text) colors with calculated contrast ratios.
- Assigns WCAG 2.0 pass/fail grades to each color pair, highlighting compliant combinations for accessibility requirements.
- Supports batch testing of multiple colors simultaneously, avoiding manual checks for individual pairs.
- Allows real-time adjustments to colors and immediate grid regeneration for iterative testing.
- Provides export options and URL-based sharing of generated grids without tracking or analytics.
How Contrast Grid Can Be Used
- Designers input design token ramps or palette HEX values to verify accessibility across light and dark modes during color selection.
- Developers paste CSS variables or Sass maps to check text readability on various backgrounds before implementation.
- Teams test UI palettes by entering foreground and background sets, reviewing the grid for failing combinations needing adjustment.
- Accessibility audits involve loading multiple color combos to document compliance with WCAG minimum contrast levels.
- Branding projects use it to pair accent colors with neutrals, ensuring legibility in digital applications.
Who Is Contrast Grid For?
Contrast Grid serves UI/UX designers, front-end developers, and accessibility specialists working on web products who need to validate color choices against WCAG 2.0 standards. It fits teams building design systems, handling palette creation, or conducting compliance checks, particularly for projects requiring batch contrast analysis over single-pair tools. Those managing design tokens or ensuring inclusive digital experiences find it suitable for quick, visual overviews.Visit Contrast Grid
