Amazon’s Alexa voice assistant has been able to change the color of smart bulbs for a while, but it was in a roundabout way. You had to first setup a scene with a new color and then ask Alexa to activate the scene. Now Alexa can finally just directly change the color of a smart bulb.
You can say “Alexa, set the bedroom light to orange” to select a specific color, but what’s probably more useful is the ability to say “Alexa, make the living room light warmer/cooler” to adjust the color temperature from a blue-ish white to an orange-ish white, and vice versa. You can also say “Alexa, set the kitchen light to cool/warm white” if you want a specific temperature of while. The new ability is already available with Philips Hue, TP-Link, and Lifx bulbs. You just need to have the respective Alexa Skills enabled.
