It's like a colorless line on a pregnancy test where a positive line would be, you usually get them if your test is sat for a couple of hours although you can get them after a short amount of time they can be mistaken for a bfp
Hope that helped if it made any sense at all
They are usually colorless like a grey colour no pink in them at all blue dye tests are the worst in my opinion because there evap lines are blue which is very confusing!! Blue dye evaps are blue very thin and off center they are very easily mistaken for bfp's that's why on tests they say not to read the results after 10-15 mins
