software aids colour design for colour blindness

In a previous post I talked about colour blindness and the possibility of using coloured lenses to improve colour discrimination for suffers of colour blindness – http://colourware.wordpress.com/2009/07/04/colour-blindness-news/

The task of designing images or copy that are legible to colour-blind users is a major concern in design. In the past I have used websites that allow you to submit an image or even a whole website and a simulation of how it might apear to a colour-blind viewer would be produced. Today I came across a really great tool called Color Oracle – see http://colororacle.cartography.ch/. This tool is free to download and runs on Windows or Mac systems. Once installed it runs in your system tray and allows you to simulate various colour-blindnessc conditions. The software is free to download and claims to use the latest algorithms for simulating colour-vision impairments.  Below is one of my images and a simulation of how it would appear to someone with tritanopia.
