Hi

You can find all about Jinja filters here [https://docs.ansible.com/ansible/latest/user\_guide/playbooks\_filters.html](https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html)

But you can convert a list to a string using

```auto
{{ list | join(" ") }}

```

This will add a space between each element. I am not sure if that is what you need.

```auto

```

Try the join filter {{ layer.bgcolor | join(' ') }}. It is fruitless to apply the list  
filter to a list :-).
