Colour Temperature in Light Automations

Hi,
It would be nice if the colour temperature of bulbs (here accessed using Zigbee2MQTT) could be set with automations in the same way that the bulb brightness can currently be set.
For example - turn on the bulb to 100% brightness and XXXX value for colour temperature at 8AM.

Thanks for all your work.

You can already do this with the color_temp attribute. See the docs → Light - Home Assistant

E.g.

service: light.turn_on
entity_id: light.xy
data:
  brightness: 80
  color_temp: 200
