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.

Essentially that's what my Color Segmentation by Delta E tutorial does: http://www.mathworks.com/matlabcentral/fileexchange/31118-color-segmentation-by-delta-e-color-difference

I hvae several color detection programs uploaded to my File Exchange. You might want to take a look at them: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

Was my answer to Sivakumaran not the right answer?

Why don't you try the Color Thresholder on the Apps tab or the tool ribbon?
