It would also be possible to support more than 3 if you are willing to accept some ambiguous pixels.
You could give each candidate a colour and then blend the colours in proportion to the probability. For a method which has reasonably sharp edges to the win regions, this could be reasonably effective. For something where all candidates have a reasonably high probability over the entire diagram, it wouldn't be as effective as you would have mixing of colours. However, for a method which gives the winner close to 100% for most of the diagram, then only in the border regions would there be mixed pixels. ---- Election-Methods mailing list - see http://electorama.com/em for list info
