This is great, especially the SF example as it reminds me of Brian Lotti's paintings [1]
A common technique for painters is to establish areas of colour in the scene that are similar even though the eye perceives them differently. For example the shade beneath a tree - while complex in reality - can be easily represented with a single stroke of darker colour.
Zooming in to the SF example [2] you begin to see how this scene could be painted, which makes me think this tool could be a useful guide in painting tutorials.
