As designers, we often obsess over the perfect palette. However, a beautiful interface is a failure if it isn't accessible. Ensuring proper colour contrast isn't just a "best practice"—it’s a fundamental requirement for inclusive design that allows users with different visual abilities to navigate our products effectively.

The Science of Seeing

Accessibility standards (WCAG) provide us with a grading system to ensure our text is readable against its background. Whether it is Regular Vision, Protanopia (red blindness), or Deuteranomaly, our job is to ensure that everyone can perceive the information we present.

Tools for the Modern Designer

To move beyond guesswork, I’ve curated a toolkit of resources that every professional should use:

• WhoCanUse: A deep-dive tool that shows how color combinations are perceived by people with various forms of color blindness.
• Contrast: A handy Figma plugin for real-time checks within your design workflow.
• Accessible Brand Colors: This tool generates a chart to show how your entire brand palette can be used together while remaining ADA compliant.
• ButtonBuddy: A specialized generator that focuses specifically on creating accessible button styles.
• ColourContrast.cc: A quick and reliable web-based checker for WCAG AA and AAA grading.

The Bottom Line: Don't design for yourself; design for the widest possible audience. Accessibility is what separates a "decorator" from a true "Product Designer".
