Hi,

I saw this question and the answer:

Q: Can voice commands other than: ON, OFF and DIM/BRIGHT be used?
A: NO, the ha-bridge emulates a Philips HUE bridge. The interactions between a Philips HUE and and Amazon Echo are determined by Philips and Amazon. They are not changeable by the ha-bridge, so only: ON, OFF and DIM/BRIGHT verbal commands are available.

Im using Domoticz with Homebridge. Homebridge have a option to connect it with Alexa.
When devices discovered (output from Homebridge) you can turn bulbs on/off/dim and colour change.

Here the site of how this works:

So my question: Would it be possible to let it work ? To change colour as well within HA Bridge using Alexa in future... :)
