Ordnance Survey produces first maps for colour blind people
Europe, May 14 2011
UK: Colour blind people will soon be able to navigate the countryside with special maps created by Ordnance Survey.
The maps, made with help from the Royal National Institute for the Blind, have one palette with shades that sufferers can see.
Once drawn, they were put to the test by colour blind volunteers. The scheme will eventually be used across the organisation’s entire range of maps as they are also suitable for those with normal sight.
An OS spokesman said yesterday: “Those who are red or green colour blind could not work with some colours on our normal maps.
“We are very proud of the progress that we have made. It will take our maps to a new level.”
Researcher Ed Mainwaring added: “The key is to differentiate between features. There needs to be contrast. You could use any colour as long as the contrast is great enough.”
Colour blindness affects around one in 10 men and one in 100 women across the UK.
Researchers believe the scheme could be used for websites, signs, classrooms and for workers in frontline emergency services.
