Red is everywhere in Montmartre

We had arranged to meet up with other members of my photography club for an outing on the theme of “monochrome.”
I picked a red marble. Others picked green, yellow, or blue.
So I had to wander around the Montmartre area for about two hours to find subjects to photograph, with a predominance of red.
I was lucky, because anyone who has ever visited the Montmartre district in Paris will have noticed that many of the shop fronts, restaurants, and bars are predominantly red.
In the surrounding streets, a number of buildings also have walls and doors that are at least partially red.
