|
| Monitors, even modern ones, don't 100% convert their backlights

| only use dark.
|
| Anyway dark mode without red tint isn't really helping with the

|

| Just a note to avoid confusion: Lunar serves a completely

|
| f.lux changes the colour temperature by altering the Gamma

|
| Lunar's main function is controlling the hardware
| brightness/contrast/volume/input/colors of external monitors

|
| macOS also has a native approach to f.lux called Night Shift. I
