Why are most SLR bodies black?

In the past, cameras with metal bodies were all natural metals, and there was no technology to paint other colors on the metal. Photographer Leibson is a Leica user. He thinks that black is more low-key than silver, and it is not easy to attract the subject when taking pictures, which makes the subject feel uncomfortable (at that time, taking pictures was not as common as it is now, just like taking pictures when the camera was not common when I was a child). Just with the technology of painting color on metal, I made a black Leica camera for Leibson, which is the first camera painted black in the world, so I chose black later.

After all, black is relatively low-key.
