Pink and Blue dye?

Question

I'm just curious as to what the difference is to pink and blue dye tests are? And what ones are better? Only been ttc for 3 months so very new to this!

Answer

I don't know exactly what the difference is but I know that blue dye can give false positives. 
Pink dye is much better and normally the tests that have pink dye have a greater sensitivity and will show up positive before the blue ones.
