i got hue bulbs (adjustable white) for: - lights turn off at night/when i leave - lights turn on when i get home - i can ask google or siri to turn them on or off as i am doing other thing as for the colour ones? I have on on my deck, its blue. sometimes i change it to another color if i'm asked but otherwise i can't find any use for the color ones.
