Blue sky gives a blue cast to everything in daylight. Before humans learned to control fire, light after sunset was typically very dim – moonlight or starlight. Fire gave humans relatively bright light after sunset, but it still differed from daylight in having a red-yellow cast. First open fires, & later candles, oil lamps, kerosene lamps & incandescent electric light all have a red-yellow cast.

More recently, fluorescent & LED lighting has exposed us to light with a blue cast after sunset. TV, computer, phone & other screens, usually have a blue cast too.

There is evidence that these blue lights after sunset can have negative consequences for human health^1,2.

If most of your evening screen exposure is to a device with a HDMI interface, help may be at hand in the form of the Drift TV.
