Is an EVAP line thinner than a positive? An evaporation line is colorless and doesn’t have even the faintest of color to it. On the other hand, a positive line has color, usually given pink in most pregnancy sticks. Even if it’s a faint pink, it could be a sign of pregnancy because sometimes the hCG level in the urine could still be low.
