Which item indicates that filters are applied to a set of results?

The indication that filters are applied to a set of results is represented by an orange filter icon in the field column header. This visual cue directly signals to users that specific criteria have been used to narrow down the results displayed in the list. It is standard practice in user interface design to use color coding to convey information quickly and effectively. The use of an orange icon suggests that something is indeed filtered and allows users to recognize at a glance which category or field has filters enabled.

In contrast, other options may provide hints about filtering but lack the immediacy or specificity. For example, a blue filter icon may indicate the potential for filters to be applied but does not confirm their current active status. A popup notification regarding applied filters can be useful, but it typically requires user interaction to see and may be overlooked. Changes in the search results count do suggest that filtering might have occurred; however, it doesn’t indicate which filters are actively applied or provide guidance for adjusting them. Thus, the orange filter icon provides the clearest and most direct indication of applied filters within the results.
