Good contrast keeps digital typography and physical print graphics readable for everyone, accommodating varied lighting conditions, low-vision readers, and high-glare environments.
Enter any six-digit or three-digit hex colour code or click the colour swatch to select a shade visually. The contrast ratio and WCAG evaluation update automatically. Large text is defined by WCAG as 18pt (approximately 24px) or 14pt bold (approximately 18.5px bold). A minimum score of 4.5:1 is recommended for standard body typography.
