Hi Rick,
On iOS you can use the Shortcuts app to do this.
You can do this under the Automation tab in the Shortcuts app. There you can create a new Automation that runs when you get a message. Select a person. Then add an action for the Hue Essentials app (search for Hue Essentials and configure an action)
There is also some information here: How do I use Siri Shortcuts?
Note that the premium version of Hue Essentials is required for the shortcuts.
Let me know if you have any questions.
