Everyone perceives color differently

As Joseph Albers once said, "In order to use color effectively it is necessary to recognize that color deceives continually." This decisiveness, of course, is a spectrum. We can be deceived from the light around us all the way to physically seeing differently (color blindness)  How can we design for a world where everyone sees different colors and those colors have different meanings? Through the lens of an infographic below, I will discuss best practices for using color. For this example I show both the most common vision and what it would look like if you had deuteranopia, a green deficiency. 

1. Use colors with higher value contrast

2. Do not just differentiate by color

3. Do not separate key information
