In today’s digital-first world, accessible design isn’t a luxury — it’s a necessity. As designers and developers, we carry the responsibility of ensuring that websites are inclusive, functional, and usable for everyone. One of the most overlooked yet critical aspects of web accessibility is color contrast. Whether you’re crafting a sleek UI or building out a vibrant brand experience, color choices can either empower or exclude users.

Why Color Contrast Matters

Color contrast refers to the difference in luminance between text (or other elements) and its background. For someone with perfect vision, a light gray button on a white background may seem subtle and elegant. But for users with low vision, color blindness, or those viewing your site under poor lighting conditions, that button could be completely unreadable.

The Web Content Accessibility Guidelines (WCAG) provide clear rules to ensure text is legible:
• Normal text should have a contrast ratio of at least 4.5:1.
• Large text (18pt and bold or 24pt and regular) should have at least 3:1.
• Icons and UI components (like form fields) must also meet a minimum contrast ratio of 3:1.

Failing to meet these standards means you’re leaving users behind — particularly the 1 in 12 men and 1 in 200 women globally affected by some form of color vision deficiency.

Common Accessibility Pitfalls

Even experienced designers sometimes fall into these traps:
• Using trendy but low-contrast color palettes
• Prioritizing brand colors over usability
• Relying on color alone to convey meaning (e.g., red = error)
• Not testing color accessibility on real screens or in context

This is where tools like Hexto.io become indispensable.
