One of the most important factors in presentation design is color combinations. There is always a but! One in twenty people is colorblind. This challenge could be incorporated into your presentations.

Color Blind Awareness states that color blindness affects one in twelve men (8%) and one in 200 women (0,5%) respectively. An estimated 300 million people are color blind worldwide. Bill Clinton, Prince William, and Mark Zuckerberg are some of the most famous color–blind people.

Optimizing your graphics design and data visualization can make them more accessible. Contrary to popular belief more than 99% can see color. However, they may not see it the same way that normal people who aren’t affected by color blindness. Your website will be more appealing if you use a color-blind friendly palette.

What is Color Blindness and How Does It Happen?

When you are unable to see colors properly, called color blindness or color vision deficit, it is also known as color blindness. This condition is also called color blindness. It is when a person cannot differentiate between certain colors. This is usually between reds and greens, but occasionally it can also occur in blues.

Two types of retina cells can detect light. These cells are known as rods and cones. They are located near the center of your eyes and detect color. There are three types of cones that see color: blue, green and red. These cone cells provide input to the brain that determines our perception of color. You can develop colour blindness later in life, although it is more common to be born with. A more serious condition can be indicated by a change in your color vision. An ophthalmologist should be consulted if there is a marked change in the color perception.

Why is color important for data visualization?

Data visualization is a key factor because it helps you highlight important information and encourages information recall. Different color‘s can be used to separate and delineate different data points in a visualization, so viewers can clearly see significant differences or similarities. You can also use it to stimulate emotions through color psychology.

How do you design charts using a color-blind friendly palette?

Do not use complex color combinations.

You should plan your color scheme in advance. This will help you avoid making your infographics or charts unaccessible for color blind users.

Avoid color combinations for color blind users:

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

You can adjust the colors so that one color is extremely dark and the other very light. This will allow you to create contrast.

Adding shapes

To outline different content types, you need to use different sizes and shapes. Color blind people reported difficulty seeing the differences between the two colors because they blur together. They did however note that high contrast and thick lines could help them distinguish. To ensure that your content is easily readable, increase the contrast and thicken lines to at least 2px.

Design your color scheme

It is strongly recommended that you use a consistent color scheme for all content if you are creating a color palette that appeals to color blind audience. It is important to keep your brand and project colors consistent. You should choose the right colors to reflect your brand and use them throughout your visuals. You don’t have to compromise the aesthetics of your brand by designing a colorblind friendly palette.

Add symbols and text labels

Make text labels descriptive and prominent by using them. These labels will help users with normal vision to lessen strain on their eyes.

Icons and symbols are great for making your designs more accessible. They visually punctuate a message, without having to rely on color.

Last, but not least: Always underline hyperlinks and never underline regular text. To make your content easier to read, hyperlinks should be the same color as the text and highlighted. Users with similar vision will notice these hyperlinks faster.

Different shapes, patterns, textures and labels are possible

It is best to use one color to distinguish the data series so that everyone can understand your plot. This design ensures that all colorblind readers can understand the plotted data regardless of their particular circumstances. The chart will remain clear even if printed in black and white (no gray shades).

Use high contrast colors

Most people who are colorblind don’t have to worry about contrast. To make the contrast stronger, you can change the hues of your colors. You can play with different hues and levels of saturation.

Conclusion.

The main reason why many people are still creating colorblind-unfriendly data visualizations is not that it is hard to avoid but actually because they may have never thought about it in the first place. Combining these elements will make your designs more accessible for color blind people. Your work will have more impact if you interact with more people.
