Please explain so I don't have to guess: So you "segmented" the color image into 3 color planes, like this:

% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);
greenChannel = rgbImage(:, :, 2);
blueChannel = rgbImage(:, :, 3);

I wouldn't really call that segmentation, but whatever.... Now I have to figure out what are "similar color regions". I have no idea what this is. Do you mean pixels that have fairly similar gray value in each of the 3 color channels? If so, you're basically looking for neutral colored regions (black, gray, white) and you can just look for low saturation

hsv = rgb2hsv(rgbImage);
saturationImage = hsv(:,:,2);
neutralColors = saturationImage < 3; % or whatever value you want.

Now you say you want to merge them, and this is where I don't even have a good guess as to what this means? Merge intensities? Merge spatial regions? I have no idea.
