Why Contrast Matters?

Color contrast is the difference in light between any two colors. In web design, it specifically refers to the difference between text (foreground) and the background.

1

Readability: Good contrast helps everyone read your content, especially in bright sun or low-light environments.

2

Inclusivity: People with low vision or color blindness rely on strong contrast to distinguish text from backgrounds.

3

Legal Compliance: WCAG 2.1 contrast standards are often legally required under ADA and the CA Unruh Act.

"Accessibility is not a feature, it's a fundamental right. Designing with high contrast is the first step toward digital equity."
