Technical Guide

Accessibility isn't a feature—it's a requirement. Designing with color blindness and low-vision users in mind ensures that your content is inclusive for everyone.

WCAG Guidelines

The Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Our color picker tool provides the exact HEX codes you need to verify these ratios.

Color Blindness Simulations

Protanopia (red-weak) and Deuteranopia (green-weak) are the most common forms of color blindness. When designing buttons or critical UI elements, never rely on color alone to convey meaning—use icons and text labels alongside your palette.

Building an Accessible Palette

Start with your brand colors, then use our palette extractor to find contrasting secondary colors that meet the 4.5:1 threshold against your background.
