List in script variables undefined

I’m looking to establish a list of colors in script variables, and then iterating over that to determine the next color my lights will be. However, when the list should be used in the template, it comes in as undefined. I thought variables could be any valid yaml type?

light_on:
  description: "activate lights in multiple rooms"
  mode: single

  variables:
    entities:
      office:
        lights: light.office
        colors:
          - type: color_temp # cold
            color_temp: 153
      living:
        lights: light.living_room
        colors:
          - type: color_temp # cold
            color_temp: 153
          - type: color_temp # warm
            color_temp: 454
          - type: color # Gold
            xy_color:
              - 0.496
              - 0.473
          - type: color # AntiqueWhite
            xy_color:
              - 0.357
              - 0.348
      bedroom:
        lights: light.bedroom
        colors:
          - type: color_temp # cold
            color_temp: 153

  fields:
    room_fragment:
      description: "fragment of room name to affect"
    event:
      description: "Hue event id"

  sequence:
    - service: system_log.write
      data:
        message: "{{ entities[room_fragment]['lights']['lights'] }}" #< works
    - service: system_log.write
      data:
        message: "{{ entities[room_fragment]['lights']['colors'] }}" 
#< Error while executing automation automation.home_light_on: UndefinedError: 'colors' is undefined

Accessing the lights property works fine, but colors is undefined. When I look at entities[room_fragment] I can see the colors property is there, but I can not access it. Any ideas?

Thanks in advance.

Not sure how entities[room_fragment]['lights']['lights'] “works.” Where do you see lights under lights?

I would they should be:

  sequence:
    - service: system_log.write
      data:
        message: "{{ entities[room_fragment]['lights'] }}" #< works
    - service: system_log.write
      data:
        message: "{{ entities[room_fragment]['colors'] }}"

Or even:

  sequence:
    - service: system_log.write
      data:
        message: "{{ entities[room_fragment].lights }}" #< works
    - service: system_log.write
      data:
        message: "{{ entities[room_fragment].colors }}"
