On my car it's white at the front (where ANPR cameras look). The yellow 
one is on the back.

That makes a lot of sense, so you are voting for the centre being 

On my car that's probably going to be all five characters (so not 
anonymised at all), but I can't complain as I've got a personal plate 
precisely so I'm more recognisable!

[Actually, I got the plate because I was fed up having to remember a 
short-lived random sequence to recite every time I bought petrol with a 
credit card in the 80's, but one does become attached to them].
