Use RGB color selector as input parameter in Blueprint - help needed

Configuration Blueprints
1

I would like to create a blueprint that allows the user to enter RGB colors for a lighting automation. I would then like to use these input parameters in the automation. Unfortunately, this does not work.

I have created the RGB color selector:

rgb_color_1:
  name: Color 1
  description: The start-color of the sunrise simulation
  default: [112,21,0]
  selector:
    color_rgb:

And declared these as input variables:

variables:
  rgb_color_1: !input rgb_color_1

Now I want to call the variables in the code:

sequence:
- service: light.turn_on
  data:
    entity_id: '{{light_entity}}'
    rgb_color: '{{rgb_color_1}}'

Unfortunately, this does not work.
I am still relatively new to .yaml, so I would be very grateful for simple solutions!

“This does not work” doesn’t help us or you. How does it not work? Error messages in traces? Error messages in the logs? Type of light and integration? And post the complete code.

Oh, sorry!

With ‘Unfortunately, that doesn’t work.’ I meant the following:
If I execute the code as I have written it above, the selected light simply remains off. However, no error messages are displayed.
If I manually enter values for the rgb_color variable in the sequence, the automation works.

There’s a lot of code in your brightness template. Does it produce a value guaranteed to be at least 1? If the light is off and you only try to set a color without also specifying brightness or brightness_pct, or you specify it as 0, nothing will happen.

Maybe it’s text that looks like a list, try casting it as a list.

`'{{rgb_color_1 | list}}'`

Also I have this if it helps you at all…

Thank you very much! The trick was to format the variable as a list. Now the automation works as it should.
