Screen Colors Filter — Color Tint & Dim HEV Block 4+

There are a bunch of screen dimmers out there, but most of them turn off briefly when you slide between desktops and full screen apps, momentarily blinding you. This one does not do that.

There are a bunch of screen tinters out there, but most of them use what would probably be considered the “Normal” blend mode in Photoshop, which adds color to everything, including solid black. You can see it in their App Store screenshots. Black should stay black. With this app, it does.

It doesn’t work when F.lux is running. No biggie, they kind of do similar things anyway.

The 'Invert' option doesn’t work. No biggie, ^⌥⌘8 is already built into macOS.

None of the color options are quite right, unfortunately. Too green. If the pro version had a full HSL color picker, I would buy it in a heartbeat. If it let you pick a different tint for each monitor (to color match them), I would pay double. And if it let you pick a daytime tint as well as a nighttime tint (so the monitors stay color matched), and faded between them automatically like F.lux, I would pay triple. Keep it relatively bug free (not glitching out when switching desktops is a good start - keep that up) and throw in a bunch of configurable global keyboard shortcuts, and I’d have no problem throwing down a $20.

I’ve used a few other blue-light-filter night screen apps, and usually you can’t adjust the color or dimness of the screen; this one gives you a lot of choices so you can pick the one that bugs you least, and it has a dimness slider. Intuitive and easy to use - just choose on setup to put an icon shortcut on your top menu bar and it’s an easy one-click dropdown panel that doesn’t interrupt what you’re doing. I don’t think it’s hard to find as some other reviews say - maybe if you have a ton of icons up there it’s not obvious which one is the filter app. It’s a monitor icon. I’ve also never had problems with it crashing which seems to be the other major problem people have. I’m using it on a MacBook laptop and maybe on your phone or iPad it’s different. Anyway on my laptop it’s been handy and easy to use. I recommend it. Save your eyes and your sleep!

This really works well, most other programs I've tried just put a layer in front of the screen which doesn't do a great job of cutting brightness, like if you're in a dark room.... BUT if the monitors go to sleep, when you wake it's canceled, which if you're in a dark room, blinds you. That fix would make this 5 stars.
