Hi, I have a number of photo images which I need to convert to 6 specific colours and pixelate the image and then sit on a grid (like if you were to make an image using a Rubicks cube to define colour and the grided system). How would I do this? The grid needs to be 450 x 450 grid cubes (not pixels as I need to show the grid also). Like I say imagine you are using the rubiks cubes to make an image.
