Bubble-card and use of Themes

I am trying setup a theme that changes the background color of .bubble-range-fill that is in bubble-card integration. This is what I have in a file located in the config/themes:

theme:
  name: "Bubble Card Pink Theme"
  styles:
    .bubble-range-fill:
      background-color: "#ff1111 !important"  # Light red color

That does not work. I have never used themes, so I am not sure how to create the file properly, so bubble-card will use it.
Please help.

After some additinal research I was able to get this theme file loaded with no syntax errors:

my_bubble_theme:
  bubble-range-fill: "background: rgba(216,178,142, 1);"

I loaded the theme in the profile section, but it has no effect.
Is it possible to use themes to modify the bubble-range-fill class background?

Hi! Try this instead:

my_bubble_theme:
  bubble-light-color: "rgba(216,178,142, 1)"

This should works, don’t forget to reload your theme after that with frontend.reload_themes.

Edit: You can find all the variables in the documentation.
