One trick you can try is to convert the RGB data to IHS,
perform a gaussian equalisation on I, H, and S (separately),
and convert back to RGB.

The result should separate out your objects; the output
colors are usually pretty gaudy and separation is obvious.

I've seen this referred to as a 'color decorrelation stretch'
though strictly speaking, it does not decorrelate anything...
