Can evaporation lines have color to them?

Question

I took a test yesterday evening with concentrated urine and while waiting for it i had a family emergency and was unable to check it till much later I have had many evap lines before they are always gray and look more like an indent in the test this one is slightly pink but and barely there but i don't have to squint or anything to see it. I know i just need to take another test but i can't do that until after work today so please don't tell me to do that i will i just want some opinions now cause i have 8 hours to sit here and stare at the test wondering so what do you think

Answer 1

Anytime I have ever tested and looked at it later there was always 2 red or pink color lines. I did this both times i was pregnant.
