No "for" loop is needed. You can index with an increment of 2.

Use the checkerboard() function in the Image Processing Toolbox:
cb = 255 * (checkerboard(20) > 0); % checkerboard.
blank = zeros(size(cb), 'uint8'); % Totally black image.
% Put checkboard into only the red channel of an RGB image.
rgbImage = cat(3,cb,blank,blank);
imshow(rgbImage)
