Are all your dashboards looking bright and vibrant? Do they immediately catch the attention of anyone scrolling through? Something that draws your attention may not for others. Not everyone sees colours in the same way. In fact, 1 in 12 men and 1 in 200 women are colour blind. Approximately 300 million people in the world suffer from some sort of colour blindness. This means that in a room of 20, there is an 80% chance that there will be at least one person with a type of colour blindness.

There are 8 common types of colour blindness:
-Blue Cone Monochromacy / Achromatomaly
-Monochromacy / Achromatopsia
-Green-Weak / Deuteranomaly
-Green-Blind / Deuteranopia
-Red-Weak / Protanomaly
-Red-Blind / Protanopia
-Blue-Weak / Tritanomaly
-Blue-Blind / Tritanopia

Common colour combinations to avoid are:
Red, green and brown.
Pink, turquoise, and grey.
Purple and blue.

Before you go spice up your next dashboard, try to keep those with colour vision deficiencies in mind.

To check how your dashboard or image will look to someone with colour blindness, you can upload an image or screenshot of your dashboard to see how it would appear to them.

Similarly, if you use google chrome as your browser, you can download this extension to have a look at the image before you save it.

Using these resources, all KPI’s, trendlines and comparisons should now clearly stand apart for everyone.
