With the recent release of the Board background customization feature, it would be a fantastic addition to also have the ability to define a specific background color for individual published cards.
Currently, cards blend into the main background or rely on default styling. Allowing a dedicated background color for cards would create an elegant and harmonious contrast with the main Board background.
From an end-user perspective, this would significantly enhance visual hierarchy, make key information stand out, and deliver a much more attractive and professional interface.
