Since I grew up on the stuff, I'm going with blue. But now I think about it Green seems to be a more suitable colour, and more widely used except for Walkers.
red - ready salted
blue - salt and vinegar
green - cheese and onion
yellow - chicken
pink - prawn
brown - beef
I remember when walkers changed the colour
I picked up a green packet from a multipack, went to eat it....... T_T

Blue is for salt and vinegar. Green is for spring onion.
