I cannot find the way to globally disable color in the pre-commit output. Setting only the background color to green and not changing the foreground color does not work for my terminal with the following settings in the Xt resources (as set in the ${HOME}/.Xresources file):

Rxvt.background: black
Rxvt.foreground: deepSkyBlue

Is there a way? It would be great to respect https://no-color.org/ environment variable. And, while we are here, maybe understand the following git config setting:

[color]
        ui = never
