Do evaporation lines have color?

I got a negative, came back and found a very think BLUE line...was an evap line or faint positive? It was 30 minutes later. I thought evap lines were always gray or colorless.

  • you can never trust any reading you get on a tested test that has been sitting... what ever your first reading was that is what you are
