Building Accessible Color Systems

Color is one of the most powerful tools in a designer's arsenal, but it's also one of the most common sources of accessibility failures. In this article, we'll walk through a systematic approach to building color systems that are both beautiful and inclusive.

Why Accessibility Matters in Color

Approximately 8% of men and 0.5% of women have some form of color vision deficiency. Beyond that, users viewing screens in bright sunlight, on low-quality displays, or with aging eyes all benefit from high-contrast, well-structured color systems.

"Good design is accessible design. If your product isn't usable by everyone, it's not finished."

The 60-30-10 Rule

A proven framework for balanced palettes: 60% neutral backgrounds, 30% secondary colors for surfaces and borders, and 10% accent colors for calls-to-action and highlights. This creates visual hierarchy without overwhelming users.

Testing Your Palette

Always validate contrast ratios against WCAG 2.1 AA standards (4.5:1 for normal text, 3:1 for large text). Tools like Stark, Contrast Checker, and browser DevTools make this straightforward.
