As a web designer, your talent for detail allows you to create visually appealing color palettes and layouts. However, it’s important to remember that not everyone can see these designs as easily as you do. Over 2 billion people worldwide—more than a quarter of the global population—live with some form of visual impairment.
Conditions like glaucoma, cataracts, and color blindness are just a few examples of the challenges they face. When designing, it’s important to consider these factors and create color palettes that are accessible to everyone.
In this blog, we’ll talk about everything you need to know about accessible color palettes in detail, so let’s dive in.
What is An Accessible Color Palette?
An accessible color palette is a carefully curated selection of colors that prioritize inclusivity and readability. These palettes are specifically designed to ensure that people with visual impairments, such as color blindness or low vision, can easily perceive and understand the information presented.
By adhering to established accessibility guidelines like WCAG (Web Content Accessibility Guidelines), designers can create color combinations that provide sufficient contrast between text and background, making digital content understandable and enjoyable for everyone.
Why Does an Accessible Color Palette Matter?
Color plays an important role in how we view and engage with digital content. For those with vision problems, some color combinations can be difficult to distinguish. Using an accessible color palette ensures that content is clear, readable, and usable for everyone, regardless of their visual abilities.
Accessibility benefits not just those with disabilities but also enhances the overall user experience for all. An accessible color palette makes content easier to read and more engaging, which can boost user satisfaction and keep people coming back, ultimately helping the success of digital platforms. Let’s explore a few reasons why accessible color palettes are important:
1. Legibility
Legibility means that your content should be easy to read, including how you use color. According to the WCAG guidelines, this is known as being “distinguishable.”
For example, to make a website accessible, the WCAG requires a minimum contrast ratio of 3:1 for large text (19px or larger in bold, or 24px or larger if not bolded).
For text smaller than 18px (and not bolded), the contrast ratio should be at least 4.5:1 to meet WCAG Level AA standards.
You can use tools like color contrast checkers to make sure your content meets these requirements.
2. Inclusive
By adhering to accessibility guidelines, you can make your designs more inclusive, especially for individuals with visual impairments, ensuring that everyone can use your designs easily.
3. Compliant
Many countries and organizations have laws requiring digital accessibility. Choosing compliant colors helps you meet these legal standards. Most web developers today are aiming to achieve WCAG compliance.
3 Levels of Accessible Color Palette Design
The Web Content Accessibility Guidelines (WCAG) outline three levels of accessibility for color palettes: A, AA, and AAA. Each level represents increasing standards for color contrast and legibility.
1. Minimal Accessibility (A)
This is the basic level of accessibility. While it’s better than nothing, it doesn’t guarantee that everyone will be able to use your design.
2. Strong Accessibility (AA)
Most websites aim for AA accessibility. This level provides a good balance between design flexibility and ensuring a wide range of people can use your content. It includes guidelines for color contrast, text size, and other visual elements.
3. Enhanced Accessibility (AAA)
This is the highest level of accessibility and is often challenging to achieve. It’s typically used for websites with very specific user needs, like government or healthcare websites. AAA focuses on the most strict guidelines to accommodate users with severe visual impairments.
Remember, choosing the right level of accessibility depends on your target audience and the nature of your design. It’s always recommended to strive for at least AA-level accessibility to create an inclusive experience for all users.
Best Practices for Creating Accessible Color Palettes
Here are some of the best practices that you must keep in mind while creating accessible color palettes:
1. Evaluate Your Accessible Color Palette Needs
The first step to creating an accessible color palette is understanding your starting point. Are you working with an established brand identity or do you have the freedom to build a color scheme from scratch? Both scenarios offer unique challenges and opportunities.
If you’re bound by existing brand guidelines, don’t worry – small adjustments can make a big difference. Many times, subtle tweaks to your color palette can significantly improve accessibility without compromising the brand’s look and feel. However, if major changes aren’t feasible, consider incorporating accessible color combinations into specific design elements while using other visual elements to add color and interest.
On the other hand, starting with a clean slate gives you the advantage of building accessibility into your design from the ground up. By carefully selecting base colors, a strong call-to-action hue, and a range of neutral tones, you can create a visually appealing and inclusive color palette. Remember, accessibility doesn’t mean sacrificing style.
2. Adjust and Iterate
Finding the perfect accessible color palette often takes a bit of trial and error. Your initial choices might not have enough options or the right mix for your project. It’s important to experiment with colors within your design software to see how they look in the overall context.
Also, consider how your colors will appear when printed, as they might look different on paper. Remember to use design tools that can help you check color contrast and identify potential issues for people with color blindness.
3. Avoid Problematic Color Combinations
Using colors that are difficult to distinguish can make your designs inaccessible to people with color vision deficiencies. Some color combinations are particularly challenging, like red and green, or blue and purple.
These combinations can be hard to tell apart, making it difficult to understand the information presented. It’s important to be mindful of these challenges when choosing colors for your designs. By considering the accessibility of your color palette, you can ensure that your work is inclusive and enjoyable for everyone.
4. Remember Its Value
Choosing an accessible color palette isn’t just about following guidelines. It’s about ensuring that everyone can enjoy your designs. By selecting colors that work well together and are easy to see, you’re creating a more inclusive experience. It’s a small step that can make a big difference to people with visual impairments, making your designs more usable and enjoyable for all.
Closing Thoughts
Creating accessible color palettes is not just a guideline—it’s an opportunity to make your designs more inclusive and welcoming to all users. By thoughtfully choosing colors, you ensure that everyone can enjoy and interact with your content. Small adjustments can lead to a significant impact, making your work accessible and enjoyable for a wider audience.
