Both R and S provide images. Look at the top left 5x5 squares of color in each image. In one case that portion of the image is correct. In the other it is not. In the incorrect one 4 of the 5 rows are ok. But for some reason the 5th row fails to increase the amount of yellow. What is so unusual is that the R and S are mirror images of one another.
