Pink dye and blue dye....

Hello.

Ladies you know when people say “I want the lines to be getting darker” and from my experience it’s usually the pink dye tests I’ve seen this for. Silly question potentially coming...so I apologise in advance..but I am

Completely new to positive testing! My question is, does the lines getting darker and stronger apply to the blue dye tests too? Basically I took the same brands of test two days apart and the lines are stronger which I am going to assume is a good thing! But I’ve only ever had faint lines with a pink dye test before during IVF and they didn’t get any stronger.

Thank you for reading :)
