My first initial ideas are to form an educational book that tests for colour blindness in children and so i have started by researching in to colour blindness so i can understand it better, therefore i will be able to determine what colours are hard to distinguish between. I looked on the colour blindness awareness page and found that the most common form of colour blindness is know as the red/green colour blindess. This is when you can’t see red or green light therefore if you were to look at purple, you would think it’s blue because you wouldn’t be able to see the red in it which makes it purple. The image attached demonstrates this through different coloured pens.
