What have you tried so far, which problems occurred and which kind of help do you want? It is unlikely, that anybody will post a running code, which solves your problem exactly. But the forum usually can assist you, when you post a specific problem, which concerns Matlab.
Please add the required information by editing the questions, becauser important details are neither comments nor answers. Thanks.

I have a color difference m-file uploaded to File Exchange. It uses the well known and accepted Delta E color difference.
There is also a collection of good color files uploaded by Stephen Westland - a important leader in the color science field: http://www.mathworks.com/matlabcentral/fileexchange/36315-computational-colour-toolbox
In addition, there are many tracking demos on MATLAB Central, such as these: http://www.mathworks.com/matlabcentral/fileexchange/?search_submit=fileexchange&query=red+tracking&term=red+tracking
