Could it be thick and blue ?

Could an evap line be thick as control line and also have colour?

Basically I took a test and it had the slightest line (not even so noticeable without squinting and moving it in different angles) within the time frame, but a few hours later I looked at it again( yes I know you shouldn’t read after the time frame but I’m crazy and obsessed) 😂 the line is way more noticeable and definitely has colour so I’m a little confused.

I will be buying another test when I have to go out for a shop as we are still in lockdown and don’t really want to go out for solely a test.

Any input would be so helpful
