brew cask install iterm2
Or, if you do not have homebrew (you should ;)): Download and install iTerm2
iTerm2 has better color fidelity than the built in Terminal, so your themes will look better.
Get the iTerm color settings
Just save it somewhere and open the file(s). The color settings will be imported into iTerm2. Apply them in iTerm through iTerm → preferences → profiles → colors → load presets. You can create a different profile other than Default if you wish to do so.

When the installation is done, edit ~/.zshrc and set ZSH_THEME="agnoster"
Note that P9k had a substantial impact on CLI UX, and its legacy is now continued by P10k.
