Group object by color

Hi everybody, I want to label together the candy with the same color. The user with ginput select a point in the image, if it correspond to one of the candies I need to show all the candy with the same color.

I was able to find the point that I will call x,y .

I was also able to label the entire image but not to label by color.

The only problem is to identify the object with the same color, I can do the rest. Can you help me? This is the image.

Try rgb2ind() to do a rough labeling of the different colors.

Or try kmeans (demo attached.)
