Custom colouring for specific TAGs in Properties

Custom CSS & Theme Design
1

I use such CSS for all TAGS in Properties. It works in preview and also in edit mode.

But I can’t make any of thespecific tabs have a different color. For example, let tag IMPORTANT be red.

Can anyone advise me how to make such CSS?

.metadata-property[data-property-key="tags"] .multi-select-pill { 
    background: #F1C235; 
    color: black;
  border: 1px solid #777; 
  border-radius: 8px; 
}
