during a coffee break your friend spills coffee on your lab coat and the fabric is discolored. Is this a true biological stain or simply a compound capable of imparting color?
The difference between a biological stain and a compound imparting color is more one of use rather than effect. Both impart color, but a biological stain imparts color to a feature that we want to look at, like the nucleus of a cell, cell walls, fat cells, disease cells, etc. If we spilled, say prussian blue on a lab coat, it would be the same as a coffee stain, but applied to a sample of bone marrow, it detects the presence of iron.
