Color challenge - Black ~Indigo

Black is funny. It doesn't always look black in photos and lots of things turn black when the lighting changes. Is a shadow black? Is oxidized black still black? Is a dark room black? Is black even a color?

I went to my old University again today to look for black. After a very short time it got so hot out I couldn't stand it and had to leave. it should be illegal to rent or lease any building, home or apartment without air-conditioning. Isolating/quarentine in 90 plus temperatures? I used to have places to go that I could read and relax and cool down during heat waves. They are all closed. I'm going to have to come up with something or somewhere else to go
