What about purplish-greenish-gray?
Where do you draw your boundary?
Anyway...
A simple approach here is to define all the colours you want to detect as normalised RGB triples, and then calculate how well a particular pixel (also normalised) matches a colour. This is loosely classed as fuzzy logic.
You calculate a score against that pixel against each of your colours, and then choose the colour with the best score.
