Re: High-contrast icons

Given that IE 7 now lets you expand text and images to the size that
you like them best - rather than just the text; I'd be inclined to
start to think about icons that are easily scalable (e.g. svg) - and
concentrate far more on clarity of icons.
The biggest problem with icons for meaning is that people don't know
what they mean.
E.g. a door.
On some interfaces (esp. eLearning and/ or children) a door often means "exit".
However, if you're playing an adventure type game, then a door is
often an invitation to explore...

I'd therefore think far more about what you are trying to convey with
the icons, than how to make them high contrast. A good icon, in
anycase, should, I feel, be very simple - and you should be picking
contrasting colours anyway.
Have you seen any of the work done with rebus Symbols for those who
have difficulty reading?
See for example:
http://www.widget.co.uk - used a lot in the UK.
http://www.askability.org.uk/ (using the Widget symbols).
http://www.mayer-johnson.com/ - used a lot in the US.
