The image should look like a red square above a blue square.

new = 255 * ones(dimensions, dimensions, 3, 'uint8');
new(:,:,2) = 0;
imshow(new);
The second line sets the green channel to zero

new = 255 * ones(100, 50, 3, 'uint8');
new(1:50,:,2) = 0;
new(1:50,:,3) = 0;
new(51:100,:,2) = 0;
new(51:100,:,1) = 0;
imshow(new);
Is this what you are looking for?
