Why Are Walkers Salt and Vinegar Crisp Bags Green?

Open a bag of Walkers Salt and Vinegar and you get green packaging. Open a bag of Walkers Cheese and Onion and you get blue. Now try to explain that to someone who grew up eating Golden Wonder. You cannot, because Golden Wonder does it the other way around, and so does almost every other crisp brand. Walkers is the anomaly, and it has been confusing people for decades.

Walkers Salt and Vinegar has always been green and Cheese and Onion has always been blue, according to Walkers. They are the exception in the UK crisp market. Most other brands use green for cheese and onion and blue for salt and vinegar. Walkers has denied ever switching the colours, though the belief that they did is one of the UK’s most persistent crisp myths.

The simple answer

Walkers chose their own colour scheme when they developed their packaging, and they have never changed it. Green for salt and vinegar, blue for cheese and onion. That is it. There is no deeper explanation. Walkers did not follow the convention set by the rest of the market, and the result has been 40-plus years of confusion.

The confusion is made worse because the rest of the industry mostly does it the other way. Golden Wonder, which was the UK’s best-selling crisp brand before Walkers overtook it in the early 1990s, uses green for cheese and onion and blue for salt and vinegar. Most people grew up with both brands on the shelf, and the conflicting colour schemes have been generating arguments ever since.

Why do most brands use green for cheese and onion?

There is no industry regulation. No one sat in a meeting in 1967 and decided that cheese and onion would be green from that point forward. It is more that Golden Wonder established the convention first, and most other brands that followed broadly stuck with it. Green for cheese and onion has a loose logic to it: green evokes onion, the sharper, more herby half of the flavour pairing. Blue for salt and vinegar is harder to justify thematically but became the default by association.

Walkers launched cheese and onion in 1954, the same year as Tayto in Ireland first created the flavour. Golden Wonder followed in 1962. From the start, Walkers used blue for cheese and onion. Whether that was a deliberate point of difference or simply their original choice that never got revisited is not clear from the public record. What is clear is that Walkers stuck with it, grew to dominate the market, and left a confusing colour landscape in their wake.

Did Walkers ever switch the colours?

Probably not, but enormous numbers of people believe they did. Walkers has addressed this directly on their website. Their official FAQ states: “Contrary to popular belief, Walkers Cheese and Onion have always been in blue packets, and Salt and Vinegar have always been in green packets. We don’t have a plan to change this, as it’s signature to our brand.”

This denial has, if anything, made the conspiracy theory more interesting to people. Malcolm Green, the adman who made the first Gary Lineker Walkers commercials in the early 1990s, has said there was a Walkers advert involving a colour swap, though he could not remember the details. No such advert has ever been produced by archive researchers. The Walkers colour scheme debate has become a genuine cultural curiosity, a real-life Mandela Effect where thousands of people share a false memory that cannot be confirmed or disproven.

The most rational explanation is this: Golden Wonder was the market leader for decades, and most people’s mental model for crisp colours was set by Golden Wonder. When Walkers overtook them and became the default crisp, the cognitive dissonance kicked in. People’s memories of what colour things should be got scrambled by the fact that the dominant brand did it differently.

How the rest of the flavour colours work

The colour confusion extends beyond just these two flavours, though salt and vinegar and cheese and onion are the ones that generate the most debate. Across the Walkers range, the full colour scheme is: Cheese and Onion in blue, Salt and Vinegar in green, Ready Salted in red, Prawn Cocktail in pink, and Smoky Bacon in a darker orangey-brown. Most of these are consistent across brands. The green-blue swap is the unique controversy.

Golden Wonder uses green for cheese and onion, blue for salt and vinegar. Tyrrells uses brown and cream across most flavours. Pipers uses a darker palette throughout. The Walkers complete guide covers the full flavour range if you need a reference for what is in which bag.

Does the colour affect the taste?

Yes, genuinely. Research by Charles Spence, a professor of experimental psychology at the University of Oxford, found that the colour of crisp packaging does affect how people perceive the flavour inside. People shown green packaging reported more vinegary flavour expectations, and blue packaging prompted more cheesy associations. The colour primes what your brain expects, and what your brain expects affects what you taste.

This is exactly why the Walkers situation is so frustrating for some people. Decades of conditioning from other brands means that reaching for a green packet and finding salt and vinegar feels correct, and reaching for a blue packet expecting salt and vinegar only to find cheese and onion feels like a betrayal. The taste is fine. The expectation is the problem.

For the record, if you want to buy Walkers salt and vinegar crisps in bulk, they come in green bags. They have always come in green bags. They will continue to come in green bags. You will need to make your peace with this.
