A red screen, by evening.
Most night modes stop at amber. Dimsome keeps going, slowly, until only red light is left on your screen.
Amber is not red.
Every colour on your screen is made from red, green and blue light. Night Shift and Windows Night light turn the blue down and stop at a soft amber, so there is still green and some blue in every white you see. A red screen filter takes the blue and the green away completely. What is left is red light only, and the screen looks like a darkroom.
Slow on purpose.
Going straight from daylight colours to red is a shock, and most people switch it off again. Dimsome fades over 4 hours in the afternoon, a little at a time, so you never notice the change. You only notice that the evening screen is red and quiet.
Your clock, not the sunset.
In Iceland the sun sets around 3:30 pm in December and near midnight in June. A filter tied to the sunset is wrong half the year. Dimsome goes by when you wake and when you want the screen red, and the whole day bends around those two times.
Red, and still readable.
Text stays sharp on a red screen, and dark mode apps look calm. When you need true colours for a moment, one shortcut or Quick Settings tap takes you back to Afternoon, and on Mac the apps you pick can skip the filter.
What people ask.
Is a red screen filter the same as a blue light filter?
A blue light filter turns blue down. A red screen filter goes further and takes blue and green away, so only red light is left.
Does Night Shift go to red?
No. Night Shift stops at a mild amber, even at its warmest setting.
Can I choose how red the screen gets?
Yes. Warmth and Brightness are two sliders, and the schedule fades to the Evening setting you choose.
Does the red filter show in screenshots?
Not on Mac. Screenshots and screen sharing keep normal colours.
Tonight can look different.
Get your key, set two times, and let the evening come to your screen slowly.
