Just noticed this section. I have an applescript that inverts colors. Not the nicest way of doing it, but it works well enough:
tell application "System Preferences"
activate
delay 0.4
reveal anchor "Seeing_Display" of pane id "com.apple.preference.universalaccess"
end tell
tell application "System Events" to tell process "System Preferences"
delay 0.3
click the checkbox "Invert colors" of window "Accessibility"
end tell
tell application "System Preferences"
quit
end tell
And also can grayscale:
tell application "System Preferences"
activate
delay 0.4
reveal anchor "Seeing_Display" of pane id "com.apple.preference.universalaccess"
end tell
tell application "System Events" to tell process "System Preferences"
delay 0.3
click the checkbox "Use grayscale" of window "Accessibility"
end tell
tell application "System Preferences"
quit
end tell
Combined, it is enough to do what I want often. It's not the greatest, but I like it enough. If you want to make it orangish (like with flux, you can use Screen Shades.
I also use Shades so that I can dim my screen beyond what apple lets (and external monitors).
