Invert screen colours

Hi! I went digging through and couldn't find a way to invert my screen colours using the system accessibility settings using a mapping.

This is particularly handy when giving presentations using a terminal with a dark theme; rather than changing EVERYTHING to light theme, I can quickly switch my screen colours to be inverted for better contrast.

Is it possible to add a mapping action to invert screen colours? Thanks!

You can use the standard System Preferences > Keyboard > Shortcuts way. Set a keyboard shortcut there and then assign a trackpad, touch bar, or any other trigger to that keyboard shortcut.
