How to change binary pattern to a 3 colour pattern?

I have this fringe pattern I'm using for Fourier Pofilometry and I want to try using a colour pattern so that it will go Red Green Blue, ie, The first black will now be red, the first white will now be blue, the 2nd black will be green, etc. Can someone show me this?

Try something like this (taken from my Image Segmentation Tutorial:

% Label each blob with 8-connectivity, so we can make measurements of it
[labeledImage, numberOfBlobs] = bwlabel(binaryImage, 8);
% Apply a variety of pseudo-colors to the regions.
coloredLabelsImage = label2rgb (labeledImage, 'hsv', 'k', 'shuffle');

Replace 'hsv' with a colormap of your own creation to get exactly the colors you want. You mgiht have to remove the k and shuffle arguments also.

If you could also show me how to make a colormap that will repeat like I want it to I would also be very grateful.

I'm also getting a gap where the white part of the fringe is.
