Firstly, welcome to the Forums.
I personally have never heard or read of this, but that does not mean that the order never went out . I imagine few crews followed this order - a bit busy at the time.
Most Allied Tankers were issued coloured air recognition panels. These were large flourescent panels sewn onto canvas strips that were then tied to the vehicle. There were 3 colours - Magenta (sometimes referred to as red), Blue and Yellow - and they were to be used in a preset order/pairings for that day/week whatever. In actuallity, the preset pairing, etc proved too difficult to manage and were let go for months; The Blue panels were particularly hard to see from the air, and consequently the crews didn't bother much with any of them in the end.
Archer make these in flourescent inks see:
