Would you have a workbook to share as an example ? I feel it would help much more.
There is no way to apply a filter to everyone on one Marks card, but not the rest of the view. However calculations can filter their output. See Including Filters in Calculations Without Including them on the Filter Card | Tableau Software for more information.
You can also use parameters instead of hardcoded values. Like [Color] = [Color Parameter]. See Create Parameters
Hope this helps!
