(a) A sample of the most scenic images reveals that they not only contain large areas of greenspace but also large proportions of grey, brown and blue. These may be mountainous landscapes or water features. (b) A sample of the least scenic images shows that “unscenic” images can also contain green, but the presence of manmade objects may be affecting the rating. Photographers of scenic images from top to bottom: Jamie Campbell (http://www.geograph.org.uk/photo/9007), Peter Standing (http://www.geograph.org.uk/photo/211685), David Gruar (http://www.geograph.org.uk/photo/158649).

While one may expect the proportion of green in images to increase as scenicness ratings increase, we find instead that images rated highly for scenicness tend to have a high proportion of blue, brown and grey. Less scenic images tend to be mainly grey with higher proportions of black and white, but also contain more green pixels than the images rated highly for scenicness.
