What color is an evap???

Shelly • Shelly♥️

I’m so confused on evap lines with Wondfo’s. I tested at 10dpo, and 11dpo, and got a faint line within 5-10mins. Picture below is 10dpo, and pic right after. Once I came home from work it was faded a little bit, but there is still pink color to it, and I was wondering if Evaps have color? Bottom picture is 5-10 minutes after and the top picture is today. So I’m confused if it’s positive or an evap because the first picture with the faint line is within 5-10 minutes. Helpppp
