Contrast-Finder finds correct color contrasts for web accessibility
WCAG success criteria 1.4.3 requires text to have a minimum contrast ratio of 4.5 (and 3 for large text).
Contrast-Finder is a tool which computes the contrast between two colors (background, foreground) and checks if the contrast is valid. When the contrast is not valid, the main target is to suggest some correct colors contrasts.
