To demonstrate the difference between CMY & RGB color models, I used two images from Prada FW 2007 Women campaign. For the CMY color model, I printed one of the images and used a photocopier to enlarge it continuously until I found the three essential colors (C, M, and Y). For the RGB part, I chose to display the other image on a computer and found the three essential colors (R, G, and B) with After Effects. In either case, I used the method and the device that gave rise to the images in the first place to deconstruct the same images and the related color models.
