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:

-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.

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