Color Contrasting for Accessibility
Published: 2009-02-15 : (Rev. 2019-02-16)
Synopsis and Key Points:
A part of the DDA is the requirement of color contrasting many everyday objects to offer assistance to those millions with visual impairments.
There are over two million registered blind people in the UK with more than five million unregistered. 94% of those blind people can see to some degree or other be it colors, shades or distorted shapes etc. It is because of this I would like to share the importance of color and luminance contrasting to give aid to the many vision impaired people in the world.
I am forty five years of age and for most of my life, well the last forty three to be precise I was under the impression that blind people as in those with white sticks or guide dogs were totally blind.
Although I am disabled myself, It was not until I became an Access Auditor that I studied such disabilities as vision impairments that I became aware of the true facts.
There are over two million registered blind people in the UK with more than five million unregistered.
94% of those blind people can see to some degree or other be it colors, shades or distorted shapes etc.
It is because of this I would like to share the importance of color and luminance contrasting to give aid to the many vision impaired people in the world.
For example if a person with a vision impairment enters say a public WC they would find a white WC system, white walls (Probable), white wash basin and so one those facilities would be near on impossible to locate.
By painting the walls in a contrasting color those white objects stand out can be identified by most vision-impaired people.
Handrails on stairs that are the same color as the wall in another example but in this case a danger when not identified.
Simple solution again is contrast the rails in say blue, black, green in fact any color that will create a strong contrast.
Simple, yes but very effective and can be even more helpful.
A large part of the Disability Discrimination Act 1995 that became law on October 2004 is the requirement of contrasting many everyday objects to offer assistance to those millions with visual impairments.
