1. Check your colours - use a tool to assess how someone colour blind would see your colour choices.


2. Avoid colour to signal a requirement - use astrisks or something that can be easily interpreted rather than simply colour.


3. Turn up the temperature - use different colour temperatures to differentiate colour choices for those that are colour blind.

The most common is red/green color blindness, where sufferers mix up all colors which have red or green as part of the whole color. Those affected by Protan color blindness are less sensitive to red light, whilst sufferers of Deuteranopia have the same problem with green. For example, a person with Protanopia will confuse blue and purple because they can’t recognize the red element of the color purple. The third type of color deficiency, Tritanopia, is the least common and refers to sufferers who struggle to distinguish blue or yellow light. The image below shows what the rainbow may look like to individuals with each of these forms of color blindness.
