Use the Color Thresholder on the Apps tab.
Or else see the color segmentation demos in my File Exchange http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862&sort=downloads_desc

You're going to have to be a lot more explicit about what's not working. I've given you several ways that I know for a fact will detect certain colors. You just have to adjust them for the colors you want. Please read : this link.
