Change Display preferences for accessibility on Mac
On your Mac, use the Display pane of Accessibility Display preferences to make items on the screen easier to see and read, and to reduce motion on the screen.
To change these preferences, choose Apple menu 
> System Preferences, click Accessibility, click Display, then click Display.
Option | Description |
|---|---|
Invert colors | Invert colors on your display—for example, show white text on a black background—except in photos and images. To also invert colors in photos and images, choose Classic invert. If you enable color filters or turn on Night Shift, “Invert colors” is automatically disabled. |
Reduce motion | Stop or reduce the movement of elements on the screen—for example, when you open apps, switch between desktops, or open and close Notification Center. |
Increase contrast | Increase the contrast of items on the screen (such as borders around buttons or boxes) without changing the contrast of the screen itself. |
Reduce transparency | Replace the transparent effect used on some backgrounds in macOS with a darker background, to improve contrast and readability. |
Differentiate without color | Use shapes, in addition to or instead of color, to convey status or information. |
Display contrast | Drag the slider to increase or decrease the screen contrast. |
To quickly turn “Invert colors” on or off using the Accessibility Options shortcut panel, press Option-Command-F5 (or if your Mac has Touch ID, quickly press Touch ID three times).
To specify which options are available in the shortcut panel, choose Apple menu > System Preferences, click Accessibility, then click Shortcut.
