This article from Japan came about from observations during a disaster situation – in this case the 2011 Tsunami. This short paper outlines research into colours and colour combinations that are easily seen and interpreted quickly by people who have one of the colour blindness conditions.
The results of this study and other colour studies are now reflected in the Japanese standards for the paint, printing and design industries. The colour scheme-set contains 20 colours and is divided into groups depending on whether things are small scale or large scale. Bright pink turned out to be a colour for large signage, so that might explain all the bright pink signs going up around the City of Sydney (or was it just a coincidence?) For more on the colours go to the Open Journal of Social Science and download the five page article, “Color Barrier Free Displays in Disaster Situations”.
