The question is not clear. Are you talking about RGB images? Which pixel should be set to yellow? Perhaps this helps:
image1 = rand(100,100,3);
image2 = rand(100,100,3);
diffPixel = image1(51,67,:) - image2(51,67,:);
image1(51,67,:) = [1, 1, 0];

Try this first: http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer
Then come back and tell us which two pixels you want to take the difference of and which pixels you want to set to yellow. Do you want to convert your gray scale image to RGB color now? Or do you want to apply a colormap? Do you have any photos that you uploaded to tinypic.com that you can show us? You need to put some work into your question, more than 10 seconds anyway. Because as I see it, Jan has answered your question. If not, you need to explain why.

Give us some code to start with. I don't want to develop the whole app from scratch for you.
