Which color dye do you usually recommend or prefer for pregnancy tests? And why?

Personally for me I always go with the blue dye because the blue dye for me always shows up before my period is due, and the pink dye test do not show up for me until a week after AF is due. And usually just to confirm I use a digital test before I call and make my doctor's appointment. But the thing about the digital test for me, those don't ever work for me either up until at least 6 weeks. So I'm really curious to know how other women are, I see a lot of women telling other women to get a pink dye test instead of the blue dye test after they post a picture of their test asking for others thoughts and opinions. So, why is that exactly? Like I stated a second ago the pink dye test don't work for me until later on and that has been with 5 different pregnancies 🤷🤷 my HCG levels are usually pretty low at the beginning and they don't rise until about a week after AF is due, so if the pink dye test cannot detect my pregnancies with such low HCG but the blue ones do then why does everyone recommend the pink ones?
