Other than not being formatter properly, which can be fixed by you viewing this link: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup, there are no errors in the code that I can see. However I don't know what you mean by color detection. What that code does is to break the RGB image up into separate color channels and display them. If that's not what you want, then perhaps you need to look at my color segmentation/detection tutorials in my File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
