Creating a color blind friendly palette is essential for inclusive design that reaches all users, regardless of their color vision abilities. With approximately 300 million people worldwide experiencing some form of color vision deficiency, designing with accessibility in mind isn't just good practice—it's necessary for creating truly universal digital experiences.
Color is a powerful design tool that influences emotions, guides attention, and conveys information. However, when designers rely solely on color to communicate important details, they inadvertently exclude millions of users with color vision deficiencies. An accessible color palette ensures that your design remains functional and beautiful for everyone, including the estimated 8% of men and 0.5% of women with red-green color blindness.
This comprehensive guide will walk you through the principles of creating color-blind accessible palettes, provide practical tools and methods, and offer real-world examples to help you design with inclusivity at the forefront.
Understanding Color Blindness
Before diving into palette creation, it's crucial to understand how color vision deficiencies affect perception. Color blindness, more accurately called color vision deficiency (CVD), occurs when cone cells in the retina don't function correctly, making it difficult to distinguish certain colors.
Principles of Creating a Color Blind Friendly Palette
Designing an inclusive color palette requires understanding fundamental principles that ensure accessibility without compromising aesthetic appeal. Here are the key strategies for creating a color-blind accessible palette:
Use High Contrast
Contrast is your most powerful tool for accessibility. Ensure sufficient luminance contrast between foreground and background colors. The WCAG recommends a minimum contrast ratio of 4.5:1 for normal text.
Avoid Problematic Combinations
Avoid red-green, green-brown, blue-purple, and light green-yellow combinations. These are particularly difficult for people with color vision deficiencies.
Use Multiple Visual Cues
Never rely on color alone. Supplement with text labels, icons, patterns, textures, and positioning to convey information.
Different Brightness Levels
Select colors that differ significantly in lightness, not just hue. A simple test: convert to grayscale—if colors become indistinguishable, they won't work well for color-blind users.
Tools & Methods to Create Accessible Palettes
Fortunately, numerous tools exist to help designers create and test color-blind accessible palettes. These resources make it easier to ensure your designs work for everyone.

Practical Tips for Designers
Implementing a color blind friendly palette goes beyond just choosing the right colors. Here are actionable tips for creating truly inclusive designs.
Test Early and Often
Use color blindness simulation tools throughout your workflow to catch issues early.
Use Design Tokens
Create semantic color systems with tokens that define purpose rather than appearance.
Document Decisions
Create style guides explaining your accessible color palette choices.
Consider Context
Test your palette on multiple devices and in various lighting conditions.
Conclusion
Creating a color blind friendly palette isn't about limiting your creative options—it's about expanding your reach. An accessible color palette improves usability for all users, not just those with color vision deficiencies.
By implementing the principles and tools outlined in this guide, you can create beautiful, functional designs that are truly inclusive. Remember that accessibility is an ongoing commitment to serving all users equally.
