I don't post for the fun of it but to give 100% correct answers!
" Black as night" Sounds ridiculous in this context. In the context you have recently given, my suggestion is spot on! See literay examples here!!!!!

Yes,it is definitely about a person.
The story takes place in Angola where black-mestizo problem is still quite present; a presumably middle/upper class lady is describing a policeman with those words, however she doesn't say it out loud. She shows a certain level of racism and because these are her thoughts only, I thought that 'black as the night' would be the best option, even if it is racist. I feel that the context requires it to be said, as the emphasis is put on the blackness.

'black as the night' to describe a person is outright racist. 'Darkest ebony' would be better in the 21st century.

Tem certeza de que se fala de alguém? Não se estará falando de escuridão cerrada?

Jet-black remete-me a cor dos cabelos.
Pitch-black a escuridão.
Se de fato se refere à cor da pele, black as the night é uma ótima opção.
