How do I make the screen all red (no green, no blue)?
Under Tinting, move the first slider all the way to Vivid and choose Red as the tint. This will remove all the green and blue light, at least as much as your screen makes it physically possible.
What is the use of the « Apply to color profile » option?
Sometimes, another app or a system event (such as plugging a new screen) can reset colors. This reset restores the curve using each screen’s color profile. By changing the color profile, Black Light Pro ensures such resets won’t affect the effect it has applied. Otherwise the effect would vanish for a few seconds until it gets reapplied by Black Light Pro.
Changing the color profile forces all windows on screen to be redrawn, even if Black Light Pro’s change wouldn’t really need it. This can make the computer a bit sluggish after a transition or a change in the effect’s settings, especially when a lot of windows are open.
Note: This option is not available on the Mac App Store version of the app due to sandboxing restrictions.
Black Light Pro closed abnormally and the effect is still in place
Black Light Pro restores the color profile when it quits. If you force quit the app, or if it crashes, it won’t have a chance to restore the normal profile. To fix things, you can relaunch Black Light Pro, wait a few seconds, then quit it. Alternatively, you can open System Preferences, in the Screens pane, under the Colors tab, and choose your normal screen color profile there.
What is different in Mac App Store version?
There’s one difference. The version from the Mac App Store cannot apply the effect to the color profile due to sandboxing restrictions imposed by the Mac App tore.
Can I use the direct version if I purchased from the Mac App Store?
Yes! The direct version Black Light Pro can recognize your Mac App Store purchase. For this to work, you must first install from the Mac App Store and launch the app at least once. After that you can replace the app with the one downloadable on this website and it should recognize the purchase.
I already purchased Black Light, do I get a discount?
Yes, but you must purchase using the same method.
On this website, to get your discount, check the Upgrade from Black Light checkbox on the purchase page.
On the App Store, purchase the Black Light Pro Upgrade Bundle. When buying a bundle, the price of your previous Black Light purchase will be taken into account and make you save.
