Many neighbourhoods did not convert to sodium lights until the 70s and 80s.
For the better part of the 20th century we used mercury-vapor street lights, which bathed the streets in soft blue light. The complete lack of red wavelengths in these lights would make a red car look black, and made humans look like vampires.
