Filter Rows by cell color fill

Abbey H.

I would like to be able to filter rows by a color of fill certain cells have. Often I'll set up a flag and used that to apply a conditional formatting to a cell. For example, if a cost over time increase, it gets flagged as red. I'd like to be able to sort out all "red" rows.

I'm sure this has been suggested before; however I do not see it and feel like it would be basic to implement.
