Use color filters on Mac
You can apply a color filter to adjust the display colors for color vision deficiencies or to tint the entire screen to make it easier to read text.
On your Mac, choose Apple menu
Select Enable Color Filters.
Click the “Filter type” pop-up menu, then choose a filter. Color Tint applies a tint to the entire screen.
For most filters, you can adjust the intensity; as you do, the pencils reflect the change to help you determine the setting that’s right for you. If you choose Color Tint, click the color box to choose the color of the tint.
Color filters can change the look of items such as images, pictures, and movies.
To quickly turn Color Filters on or off using the Accessibility Shortcuts panel, press Option-Command-F5 (or if your Mac or Magic Keyboard has Touch ID, quickly press Touch ID three times).
