I just dont understand

I took a blue dye and red dye last night! BOOM both a clear as day faint pink positive. I take the same kind of tests in the morning and the blue dye was darker but the red dye was lighter. I took the same too again tonight. Blue dye lighter the this morning but darker then last night. And now i added a other different blue dye and that one is a faint positive and then red dye that i just took is A faint positive the same as the morning! Wtf is going on!?!?!?!??!
