if you are using terminal:

• terminal: iTerm2
• $TERM variable: xterm-256color
• color configuration (:set t_Co?): 256
  if you are using Neovim: no
• does it happen in Vim: yes

screen shot (if possible)

Disable your terminal theme in iTerm, it's overriding colors.

set termguicolors

Try to add this after

set t_Co=256

It told Vim to use 256 colors and enable true color support.At least it works in Windows Terminal

[chrisbra]

you either use:

:set termguicolors

(for true color mode)
or use:

set t_Co=256

to use 256colors.
