Colour is perceived when visible light falls onto biological cells located on the retina of the eye. There are three types of these cells referred to as “colour cones”. Each type specifically detects blue, green or red light. Defects in any of these cones will result in some form of colour vision deficiency (also known as colour blindness). World-wide the average prevalence in the population is 8% in males and 0.5% in females.
The PDI colour palette consists of twelve components, a foreground one which is black, a background that is an achromatic colour (a shade of grey), and ten colour components for the data to be analysed.
