Evap lines

Is it possible for a test to have an evap line that has pinkish color to it and for it to appear during the time limit? I had someone tell me that my test that everyone has said is positive was an evap line. Also keep in mind that I had taken a second test same brand and it had the same pinkish second line appear during the time limit. And both tests still have the second pinkish lines over a week later. And the person is still saying that both brand new tests were evap lines. Anyone have any insight?
