With colour being used for communication so much in day to day life, let alone if your a graphic designer, colour blindness must post regular challenges for those affected by the condition.
With the ColourAdd system, recognizing and utilizing colour is now possible.
The system proposed is based on the search of the color, not the light color RGB Ð (R, red; G, green and B, blue), because the colorblind person does not possess the correct vision of the colors, nor a tangible knowledge of how their addition works.
The system proposed is based on the pigment colour, using as basis the primary colours: BLUE (cyan), RED (magenta), YELLOW.
In addition to primary and secondary colours, symbols for white and black allow users to expand their colour range into the dozens, as well as using shades of grey and specialty symbols for gold and silver.
I posted an article some time ago on Logo designs not for the colour blind. It looks like they may soon be using colour after all.
