Automatic Color and Brightness Adjustment

Some select smart bulbs have color temperature settings, which can shift how “warm” or “cold” the light is to mimic natural light when needed (which is not the same as adjusting the brightness level, a more common feature). Smart color bulbs can approximate this by shifting into different shades of yellow, red, and white.

For such color temperature and color bulbs, iOS 14 will now have the option to automatically adjust the lights throughout the day to mimic the natural cycle of the sun.

In other words, growing warm lights to mimic the dawn, shifting to brighter, “colder” lights in full daylight, and down to darker, warmer tones as evening comes and the sun sets. It’s a great feature for those especially sensitive to lighting or people who want to encourage more natural sleep cycles even if they’re stuck indoors all day.
