For some reason I'm seeing more and more painted walls around. Decoration in parks, or downtowns. Here the low wall surrounding the little park is inset with panels of mosaic, but then there's the weird wash of pale pastel purple fading to white on the big wall at the back. One thing I wonder is whether at some point this section of wall was used as a downtown outdoor movie theater. The proportion of the finished section is perfect for 'scope projection, if it was originally painted flat white.
