Similar question:
or
ii=imread('1.jpg'); % load original
figure()
imshow(ii) % show orignal
newii(:,:,1)=ii(:,:,2);
newii(:,:,2)=ii(:,:,1);
newii(:,:,3)=ii(:,:,3);
figure()
imshow(newii) % show new

Doesn't this swap the Red with the Green (if it's RGB)? To swap red/blue, they would want
newii(:,:,1)=ii(:,:,3);
newii(:,:,2)=ii(:,:,2);
newii(:,:,3)=ii(:,:,1);
