I’ve been posting a lot of either signage or black and white photos lately and wanted to change things up. So here is a short series of photos that predominantly feature one primary (or near-primary) color.

A large, red, cinderblock wall. A green wooden door is set into its center, surrounded by light blue wood panel. One way street sign on the far left. — Red

Trees and leaves would've been the obvious picks for green, so I'm trying to be a little clever. I found that I had two copies of this photo—one that included more of the door frames and surrounding area, and this one, cropped so there's nearly nothing but green. There's something comforting about recognizing that the same sorts of things have caught my eye over time, and this photo has two of them—signage and large swaths of color.

Evening. Overcast sky, saturated blue clouds. Silhouettes of trees. Foreground: shadowed house with yellow light visible through windows. — Blue

Indigo's a tough one. I'm kinda guessing here. Unfortunately, I don't recall exactly where in Italy this was taken, except that it was at a point in the trip when we were doing day trips to towns in Umbria.
