How many graphic designers are colour blind? Well, we did have a designer that worked here that was colour blind! But did you know colour blindness affects approximately 1 in 12 men (8%) and 1 in 200 women in the world. In Britain this means that there are approximately 2.7 million colour blind people (about 4.5% of the entire population), most of whom are male. Most colour blind people are able to see things as clearly as other people but they are unable to fully see red, green or blue light. There are different types of colour blindness and there are extremely rare cases where people are unable to see any colour at all. So when we do any digital and print design we have to ensure what we deliver the client is 'colour-blind-friendly'.
