Is there a way to make a card background color match the label color?

I have been using Trello Cards Optimizer to do this, but that feature does not seem to be working any more. Is there any other way I can make a card background color match the label color?

Hi @Meredith Boylan ,

Are you looking for the way to color cards on the board or Trello calendar?

If it's for a calendar representation, then you may try Planyway power-up that colors cards the same color as Trello labels.
