vim - iterm2 configuration problem

Question

Why can’t I always achieve the effect according to other people’s online settings? What is displayed here is always a single tone:

Is there something wrong with me? Please enlighten me

Answer 1

Go to the Internet and search for the iterm2 theme, then load it and select your theme

Answer 2

Command+iEnter Preferences and double-click the profile you are editing to try.

Answer 3

Your Minimum Contrast setting is correct.

Try enabling x-term 256color first. If you don't enable this, there will definitely be no color.
The method is to put export TERM='xterm-256color'加到你的配置文件前几行。如果你用zsh就是加到~/.zshrc，如果你用bash就是加到~/.bash_profile
