Add visual effects to your screen to give your eyes a rest or just for fun. Customize the effects and toggle them as needed using hotkeys at preset times.

CREATE YOUR OWN EFFECTS

Each effect can include a combination of dimming, tinting, clipping, and gamma shifting. It can also invert colors and adjust HDTV brightness. Create the effects you need. Invert and turn the screen completely red if you’re into astronomy. Orange-yellow shades will help you sleep better, while blue will help you stay awake.

– Dimming: Reduce screen brightness by dimming each pixel. Used to reduce the brightness of LCD screens beyond the minimum backlight level.

– Tinting: Simulates a color filter of the selected color placed in front of the screen. Allows you to change the hue by setting the white point. Useful for giving the screen an orange glow and reducing blue light at night, but works with any color.

Clipping (underexposure and overexposure): Replace dark grays below a specified threshold with black, and light grays with white. Darker or lighter colors may slightly alter the hue.

– Gamma Shift: Makes grays lighter or darker, but without saturating them when reaching a certain threshold (unlike clipping). Useful for making subtle dark or light details more visible, for example in a dark game.

-Invert Screen: Inverts the black and white colors, creating a negative image on the screen.

– HDTV Brightness Adjustment: Adapts the image to the 16-235 brightness range used by some HDTVs when connected via HDMI. Typically, the computer should automatically adjust the output values, but this isn’t always possible if the TV is connected via an adapter.

TIMER, SUNRISE AND SUNSET ACTIVATION

Effects can be automatically triggered based on your Mac’s clock or local sunrise and sunset times. You can chain multiple transitions to change colors as you see fit throughout the day.

APPLICATION-SPECIFIC EFFECTS

Always want to use a specific effect when watching videos or playing games? You can associate effects with specific apps, and Black Light will automatically switch to those effects while the app is in the foreground… and automatically switch back when the app is no longer in the foreground.

COMPREHENSIVE MULTI-SCREEN SUPPORT

Have more than one screen? No problem. While the effect works on all screens, you can customize its settings for each screen individually. For example, this is an easy way to make a secondary screen less noticeable while performing certain tasks.

MOUSE INACTIVITY AND TRACKING

Black Light effects can change their settings after a certain period of mouse or keyboard inactivity. Use the “Vary for Inactivity” button to specify how the inactive version of the effect should appear.

If you have multiple screens, you can also use inactivity to highlight the screen your mouse is currently on.

HOT KEYS

Each effect can be activated from any application by assigning it a global hotkey. You can also customize various aspects of the currently active effect using more customizable hotkeys.

MENU

The dock menu displays a list of available effects. You can use it to enable or disable effects, even if they don’t have a hotkey. You can also move the Black Light icon to the menu bar, freeing up space in the dock.

RESTRICTIONS

Black Light will not work with a screen connected using some USB DisplayLink adapters or with an iPad connected using Sidecar.
