See my color demos in my File Exchange There are several demos where I get the values of RGB and HSV in several places. Basically you just index into an array or else use impixel().

MATLAB: How to code rbg colour intensity of an image????

you can extract all the three color planes using:

R = YourImage(:,:,1); % Red color plane
G = YourImage(:,:,2);   % Green color plane
B = YourImage(:,:,3);   % Blue color plane

MATLAB: Read three different RGB band and Swap the Band

Try this:

% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);
greenChannel = rgbImage(:, :, 2);
blueChannel = rgbImage(:, :, 3);
% Now swap around in any way you want.
newRedChannel = greenChannel;
newGreenChannel = blueChannel; 
newBlueChannel = redChannel;
% Recombine separate color channels into a single, true color RGB image.
NewRgbImage = cat(3, newRedChannel, newGreenChannel, newBlueChannel);
