Samuel Smith is known for his impressive colors in his compositions.
Among his color works, there was a group of pieces that I always return to (one even has a story written for it: https://artlords.com/stories/187) – I like to call it “The Emotional Giant Robots” for they are massive automaton-like figures being observed by tiny human-like creatures. And these bots show some pathos, either sadness, understanding or something else. Click the images for more information about them.
Heart under their metal carcass.
