John Voorhees, writing at MacStories:
The Hue app received a major update earlier this year, which significantly improved the creation of scenes. Users can pick from pre-built scenes created by designers to evoke a particular mood or create their own using photos or a color picker to control the color and brightness of a group of Hue bulbs.
With the new Siri Shortcut support, those scenes can be triggered using Siri and incorporated as actions in custom shortcuts using Apple’s Shortcuts app.
I am really excited to play with this.
