Colour Deficiency and Presentations Colour Deficiency and Presentations Presentation Transcript

  • Colour Deficiencies 3rd Year Project Results
  • What’s the Problem?A considerable amount of information is presented to computer users throughcolour without a text alternative. This means if a user is colour blind, and thereforeunable to distinguish between certain colours, this information could be lost. A recent usability study conducted by the UK Disability Rights Commission, found that colour accessibility is the second most recurring problem for disabled users whilst accessing information on the web.

Bright colours are less confusing than similar shades of a colour, with black and white being the most opposed.
