I would be wary of telling fibs to the revenue if your tank is full of unpaid tax diesel after November. There is a chemical marker in red diesel, not only the colour. This may be changed for diesel deliveries after November. So they will know if the fuel is old red or not. I am not a chemist and dont know the chemistry of it. but thats what a forum is for, to pool our knowledge for a common good.
