Worldwide prevalence of red-green color deficiency. I used the Coblis-Color Blindness Simulator to generate the varying color vision deficiency examples in Figure 4.ġ. More importantly, it will help to reduce any barriers to accessing vital information for our entire audience. Using the correct color palette and varying the style of the figures by changing the line styles (e.g., dashed) or marker shapes, can assist our readers regardless of their color vision deficiency. Hence, it is critical that we generate data visualization using the methods above to help our audience. For example, a low order might be represented by a light shade of blue, but a high order might be represented by a darker shade of blue ( Figure 1).Ĭolor vision deficiency can hinder our readers from extracting information from our data visualization. Sequential palettes are used for ordered data which are represented varying gradient levels of color. This color palette package in R was developed by Cynthia Brewer, and you can experiment with different color combinations at. Recently, I created a report using the RColorBrewer color palette, which contains three types of color palettes: sequential, diverging, and qualitative. To maximize the uptake and adoption of our tools and reports with data visualization, we need to consider using color blind friendly palettes. This can have important implications when developing our data visualization, which is meant to inform and educate.
However, people with color vision deficiency (also known as “color blindness”) are unable to experience or benefit from the use of colors in data visualization. Color has become an important element to data visualization adding another dimension of information and data. Data visualization has evolved into sophisticated interactive graphics where users can gather more information compared to simple two-dimensional graphics.
