Optimizing your graphics can help make them more accessible—and that doesn’t mean banishing color from your charts and graphs either. Contrary to popular belief, more than 99% of color blind people can, in fact, see color—just not in the same way as someone who isn’t impacted by color blindness.

First thing’s first…

What is color blindness?

Color blindness—also known as color vision deficiency (CVD)—is a deficiency in distinguishing between different colors. It occurs when light-sensitive tissue in the back of the eye—the retina–fails to properly respond to variations in wavelengths of light, which enable people to see different colors.

Although color blindness is primarily an inherited condition, it can also result from cataracts or trauma to the eye, as well as a number of diseases, including Parkinson’s, Kallman’s Syndrome and diabetes. Damage to the retina caused by aging can additionally cause color blindness.

What are the 3 types of color blindness?

There are three distinct types of color blindness:

Red/Green Color Blindness

According to Colblindor, 99% of all color blind people suffer from red/green color blindness. This is further broken down into two distinct categories:

  • Protanopia: Also referred to as “red weakness”, individuals who suffer with this variation of red/green color blindness are unable to perceive red light.

The protanopia color spectrum looks like this:

  • Deuteranopia / Deuteranomaly: Also known as “green weakness”, this type of red/green color blindness renders people insensitive to green light (deuteranomaly) or unable to perceive any green light at all (deuteranopia).

The deuteranopia color spectrum looks like this:

Red/green color blindness is inherited, and affects males more than females. The reason for this is because the genes responsible for this condition are contained within the X chromosome.

Because women have two X chromosomes, any deficiencies in one will typically be compensated by the other. Men, however, only have one X chromosome, and don’t have a “spare” to fall back on.


Blue/Yellow Color Blindness

People who suffer from blue/yellow color blindness have difficulty distinguishing between blue and yellow colors.

This particular form of color blindness–also known as Tritanopia–is far less common than its red/green counterpart. In fact, according to the U.S. National Library of Medicine, blue/yellow color blindness affects fewer than 1 in 10,000 people worldwide.

Because Tritanopia isn’t caused by a genetic trait linked to the X chromosome, it is equally present in both men and women.

The Tritanopia color spectrum looks like this:

Complete Color Blindness

People who suffer from complete color blindness—also known as Monochromacy—are unable to distinguish between any colors at all. Monochromacy is extremely rare, occurring in 1 in 33,000 people, according to Colour Blind Awareness.

Why is color so important in data visualization?

How to make the right color choices for your ux portfolio

Color plays a significant role in data visualization. For starters, colors are used to highlight important information, as well as illustrate relationships between various types of data. Color also plays an instrumental role in guiding the viewer’s eye. It can even be used to stimulate emotion through color psychology.


You can even argue that the colors used in charts and infographics actually tell the story of the data they represent. As Eva Murray writes in Forbes:

In data visualization, color sets the tone and enforces a message for the underlying visual display. It creates a certain atmosphere and can turn an unassuming visualization into an emotion-filled data story.

Knowing how to pick colors is important, but when you’re optimizing for accessibility, there’s more to consider than color theory and design composition.

HOT TIP: Venngage’s Brand Kit feature makes it easy to automatically import your brand colors and brand fonts into your design composition.

You can also use Venngage’s color picker tool to easily switch out different colors, a particularly useful tool for working with color blind friendly palettes.

How to design charts with a color blind friendly palette

1.) Plan out your color scheme beforehand

Using a color blind friendly palette doesn’t mean you need to compromise on aesthetics or strip out all the color from your charts. By planning ahead, you can ensure a color blind friendly palette compliments your design, rather than clashes.

Even with a tool like Venngage, which can drastically scale back the number of hours required to create an infographic, it’s still ideal to flesh out your color scheme before you dive in and start a new project.

Once you’ve narrowed down your color palette, you can upload your data. It’s simple with Venngage’s chart widgets. Open your chart widget, click the green IMPORT button under the DATA tab and upload your CSV file. Your chart will visualize the data automatically.

We’ve also made it easier to customize your tables now. You can present data and highlight important information without compromising the accessibility of your design.

When editing your table, you can choose the style and color of your fonts, and the background colors of your cells. You’ll find these options under the data tab.

You can also organize your text to improve the readability under the settings tab. Here you can choose how to align your text horizontally and vertically within each cell.

Take advantage of stylization features like these! After all, if it turns out your colors aren’t particularly suited to color blind people—and accessibility is important to you—it’s better to find this out before you’ve invested considerable time and effort in your design composition.

2.) Avoid problematic color combinations

How To Make The Right Color Choices For Your Ux Profile

Another reason you should plan out your color scheme beforehand is so you can avoid using problematic color combinations, some of which can make your charts or infographics completely inaccessible to color blind people.

Color combinations to avoid for people with color blindness include:

  • Red & green
  • Green & brown
  • Green & blue
  • Blue & gray
  • Blue & purple
  • Green & gray
  • Green & black

If you’re stuck and absolutely must use one of these combinations, try making adjusting the shades so one is extremely dark, and the other extremely light—most color blind people can detect contrast, so this likely will make things easier.


3.) Use highly contrasting colors

As previously mentioned, contrast isn’t an issue for most people who are color blind. Darken and lighten your colors, respectively, to make the contrast more pronounced. You can also play with different hues, as well as levels of brightness and saturation.


4.) Use patterns and textures

Using patterns and textures in your design is a great way to incorporate visual elements into your design which don’t rely on color.

Venngage’s drag-and-drop design editor features a library of patterns you can use to enhance your design and make it more accessible.

5.) Use symbols

Symbols and icons are a great way to make your designs more accessible because they can visually punctuate a message, without relying on color.

Hot Tip: Venngage’s library includes over 4,000 icons you can use to make your infographics and charts more accessible.

6.) Make your chart monochromatic

Because color blindness doesn’t impact the ability to distinguish between different shades, consider making your charts monochromatic. Using a restricted color palette will naturally mean there are fewer opportunities to use problematic colors or combinations.



7.) Keep your design clean and simple

When you’re designing for accessibility, it’s important to keep your infographics as simple and streamlined as possible. Adopting a minimalistic approach will help ensure your presentations are more easily understood, whether or not your audience is color blind.

Key takeaways for using color blind friendly palettes

Optimizing your infographics and charts for people affected by color blindness is important for both accessibility and inclusivity. It’s also possible to do without compromising the aesthetic quality in the process.

The following measures can help ensure color blind people are actually able to engage with your designs:

  • Selecting color blind friendly palettes
  • Avoiding problematic color combinations
  • Using different textures and patterns to highlight important information–not just color
  • Using symbols and icons to supplement color-coded messages, warnings and alerts
  • Using highly contrasted color combinations
  • Adopting minimalistic design to help avoid unnecessary confusion.

Combining all these elements will help make your designs more accessible to color blind people. After all, the more people you can engage with, the more impactful your work will be.
