Tell me your more experienced opinion please.
Here is a video of the process:
Note that the drops in vial-B did not land directly into the bottom of the vial and as such color was couple of seconds delayed until I physical tilted the sample so that the reagent would come into contact with the pharmacom oil down the side of the vial-B. Color did develop instantly once contact between the reagent and the oil being tested had been achieved and there is a spot on the side of vial-B where that contact first occurred (the spot is visible under the 365nm UV light). My apology for any confusion this delay may cause--This is why I post the videos though so that people may observer the process and come to their own conclusions with as much information as I can give.
