Struggling to get automation to set Globe color

Configuration
2

Instead of a Device Action, try a Service Call.

service: light.turn_on
target:
  entity_id: light.bf38be635feb9ddbfdnwzv
data:
  brightness_pct: 100
  rgb_color:
    - 255
    - 255
    - 255

NOTE
Double-check the entity_id in the example I posted. I had to transcribe it from your screenshot. For future reference, post the automation in YAML as opposed to a screenshot. For more information, refer to guideline 14 in the FAQ.
