There are two examples from MathWorks that may be useful.
The first one transforms RGB to LAB. Components A and B are colors without the disturbance of light. By considering the distance between the standard colors to colors in your figure, the fruits may be separated. We may do a little change on this example, e.g. calculating histograms of colors for different fruit. See ‘. Color-Based Segmentation Using the L*a*b* Color Space’ .
The second one collects the similar colors with clus tering technology. MATLAB can automatically generate the code that you want. See Segment Image Using Auto Cluster.

Maybe try rgb2ind() telling it that there are 6 or 7 colors (white, black, red, orange, yellow, light green, dark green) and see what it comes up with.
