Hi,

So, I have this image with this code:

img = zeros(256,256); img(:, [1:6:end, 2:6:end, 3:6:end]) = 1; imshow(img), axis on;

and I want to have 2 images, one with red channel and the other one with green channel and i want to overlap the images at 30 degree to result yellow.

Could anyone help me with the code, please?

Here it is

img = zeros(256,256); 
img(:, [1:6:end, 2:6:end, 3:6:end]) = 1; 
imshow(img), axis on;
%build RGB image
RGB=cat(3,img,imrotate(img,30,'crop'),zeros(256));
%show it
imshow(RGB); axis on;
