Yep after the reaction time which is normally 10mins it is possible for a line to come up which is normally colourless or like a dent often only seen when you hold it at a certain angle. They can be coloured, an outline or half a line or common as well.
In saying that I had alot of what I thought were evaps turn out to be EXTREMELY faint positives but with a pregnancy that only had minimal HCG and was not viable.
If any sort of line is coming up within the first 10 minutes then it is a positive, disregard what the test says after that 10mins though.
In general a faint positive should be a bit darker tomorrow so thats always a good way to tell.

Oh also I have had evaps on FR and some of them were quite dark grey and clear, others could only be seen in certain lights But this always happened AFTER the reaction time
