Designing with Accessibility in Mind: Color Contrast and Legibility

Introduction

Design isn’t just about aesthetics, it’s about communication. And if your audience can’t easily read or understand your materials, your message gets lost.

For businesses investing in brochures, flyers, signage, and other printed materials, accessibility is often overlooked. Yet, it plays a major role in how your brand is perceived, and how effective your materials actually are.

We’ve seen beautifully designed print pieces fail simply because the contrast was too low or the text was hard to read. On the flip side, when accessibility is done right, materials not only become more inclusive, they also perform better.

In this guide, we’ll break down how to design with accessibility in mind, focusing on color contrast and legibility for both print and digital.

Why Accessibility in Design Matters

Accessibility ensures that your content can be used and understood by as many people as possible, including individuals with visual impairments, color blindness, or reading difficulties.

According to the World Health Organization, over 2.2 billion people globally have a vision impairment or blindness. That’s a massive portion of your potential audience.

What Accessibility Impacts:

• Readability and comprehension
  

• User experience
  

• Brand trust and professionalism
  

• Legal compliance (in some cases)

From our experience working with marketing teams and businesses, accessible design often leads to:

• Higher engagement
  

• Longer reading time
  

• Better conversion rates

Understanding Color Contrast

Color contrast refers to the difference in brightness between text and its background. It’s one of the most important factors in readability.

What Is Good Contrast?

High contrast makes text easier to read. Low contrast makes it difficult or even impossible.

Examples:

Contrast Standards You Should Know

The Web Content Accessibility Guidelines provide widely accepted standards:

• Normal text: Minimum contrast ratio of 4.5:1
  

• Large text: Minimum contrast ratio of 3:1

Even though WCAG is primarily for digital design, these standards are extremely useful for print as well.

Why Contrast Matters in Print (Not Just Digital)

Many designers assume contrast only matters for websites, but it’s just as critical in print.

Common Print Issues We See:

• Light text on colored backgrounds
  

• Text over images with poor visibility
  

• Low-contrast brand color combinations

In our sessions, we’ve seen brochures that looked “stylish” but were hard to read in real-world lighting conditions. Once contrast was improved, readability, and engagement, improved significantly.

How to Choose Accessible Color Combinations

Best Practices for Contrast

1. Stick to High-Contrast Pairings

• Black on white
  

• Dark blue on light gray
  

• White on dark backgrounds

2. Avoid Problematic Combinations

• Light gray on white
  

• Yellow on white
  

• Red on green (especially for color blindness)

3. Test Before Finalizing

Use tools like:

• WebAIM Contrast Checker
  

• Adobe Color

Quick Reference Table

Designing for Color Blindness

Color blindness affects approximately 1 in 12 men and 1 in 200 women globally.

Common Types:

• Red-green color blindness
  

• Blue-yellow color blindness

Design Tips:

• Don’t rely on color alone to convey meaning
  

• Use icons, labels, or patterns
  

• Ensure strong contrast regardless of color

Real Insight:

We’ve worked with clients whose charts and infographics relied heavily on color differences. After adding labels and improving contrast, the materials became significantly more usable.

Legibility: Making Text Easy to Read

Contrast is only half the equation, legibility is the other.

What Affects Legibility?

• Font choice
  

• Font size
  

• Line spacing
  

• Letter spacing
  

• Layout

Choosing the Right Fonts

Best Options:

• Sans-serif fonts (clean and modern)
  

• Simple serif fonts (for longer text blocks)

Avoid:

• Overly decorative fonts
  

• Script fonts for body text

Fonts from Google Fonts are often a safe and accessible choice.

Font Size Guidelines for Print

We’ve seen cases where businesses tried to “fit more content” by reducing font size, this almost always hurts readability and effectiveness.

Line Spacing & Layout

• Use 1.4–1.6 line spacing for readability
  

• Avoid cramped text blocks
  

• Maintain clear margins and padding

White space isn’t wasted space, it improves comprehension.

Designing Text Over Images

This is one of the most common accessibility issues.

What Goes Wrong:

• Busy backgrounds reduce readability
  

• Low contrast between text and image

How to Fix It:

• Add a dark or light overlay
  

• Use solid background blocks behind text
  

• Blur the image slightly

Real Example:

We’ve redesigned marketing flyers where text was placed directly on busy images. By adding a subtle overlay, readability improved instantly without sacrificing design quality.

Case Study: Improving Accessibility for Better Results

We worked with a marketing agency producing brochures for a local service business.

The Problem:

• Light gray text on white background
  

• Small font sizes
  

• Low engagement

What We Did:

• Increased contrast to meet accessibility standards
  

• Adjusted font sizes and spacing
  

• Simplified layout

The Result:

• Higher readability
  

• Better customer response
  

• Improved brand perception

We’ve seen this pattern repeatedly, accessible design doesn’t just help users, it improves performance.

Tools to Check Accessibility

Here are tools we regularly use:

• WebAIM Contrast Checker
  

• Stark
  

• Figma

These tools make it easy to test and validate your designs before printing or publishing.

Common Accessibility Mistakes to Avoid

Using Low-Contrast Brand Colors

Even if it looks “on-brand,” it may not be readable.

Overloading with Text

Dense layouts reduce readability.

Ignoring Real-World Conditions

Lighting, print quality, and distance affect visibility.

Relying Only on Color

Always include additional visual cues.

Balancing Design and Accessibility

A common misconception is that accessible design limits creativity.

In reality, it enhances it.

We’ve worked on projects where improving accessibility actually made designs look cleaner, more modern, and more professional.

Accessibility isn’t a constraint, it’s a design advantage.

Quick Accessibility Checklist

Before finalizing your design:

• ✔ Text meets contrast standards
  

• ✔ Font size is readable
  

• ✔ Layout has enough spacing
  

• ✔ Text is readable over images
  

• ✔ Color isn’t the only way information is conveyed

Conclusion

Designing with accessibility in mind is one of the smartest ways to improve both user experience and business results. When your materials are easy to read, visually clear, and thoughtfully structured, they naturally become more effective, reaching a wider audience and leaving a stronger impression. From choosing high-contrast color combinations to selecting legible fonts and optimizing layout spacing, every detail contributes to how your message is received. In our experience working with businesses and marketing teams across the U.S., even small improvements in contrast and readability can significantly increase engagement and response rates. Accessibility isn’t just about inclusivity, it’s about clarity, professionalism, and making sure your message truly connects with the people you’re trying to reach.
