Where sea meets sky
Or where paint meets a different color paint and kinda looks like the sea and the sky.
There are so many buildings in Montmartre with multiple layers of paint in varying shades. Because the line at which the two colors meet is often rough, it reminds me of the ocean.
I've been searching for a painting of the ocean (in grays) and haven't had much luck. Perhaps I could just go with one of these.
