Control Hue Lights, linked to a Hue Base with a Tradfri Remote, linked to deConz

Hi there!
With some research in this Forum I made it, that my Tradfri Remote controls two Philips Hue Lights, which are linked to my Hue Base. It’s possible to use the main Button as toggle and the two dim buttons for dimming. My used automation code looks like:

- id: Wolken toggle tradfri
  alias: Wolken toggle tradfri
  trigger:
        platform: event
        event_type: deconz_event
        event_data:
            id: tradfri_wolken
            event: 1002
  action:
      service: light.toggle
      entity_id: 
      - light.hue_color_candle_2
      - light.hue_color_candle_1
      

- id: Tradfri Dimmer Wolken
  alias: Tradfri Dimmer Wolken
  trigger:
    - platform: event
      event_type: deconz_event
      event_data:
        id: tradfri_wolken
  action:
    - service: light.turn_on
      entity_id:
      - light.hue_color_candle_1
      - light.hue_color_candle_2
      data_template:
        brightness_step_pct: >
          {% if trigger.event.data.event == 2002 %}
            +10
          {% elif trigger.event.data.event == 3002 %}
            -10
          {% endif %}

and this works like a charm.

But how can I use the two “Hue-Buttons” to cycle through colors? Any idea?

I’m running HASS on a RaspberryPi 4.
