Crisps are a popular in the UK and different colours are synonymous with certain flavours. Common flavours such as Cheese and Onion, Salt and Vinegar and Ready Salted have been associated with over time.

Documentarian Chris Spargo posted a video on TikTok to explain why people think of certain flavours when they see the colour of a crisp packet. Holding two packets of crisps, he said: "Cheese and Onion and Salt and Vinegar. These two flavours have been popular in Britain for decades and the leading brand, Walkers, have always used this colour scheme (blue for Cheese and Onion and green for Salt and Vinegar)."

However, in 2016, YouGov research showed that 44% of people in the UK associated green with Cheese and Onion. Meanwhile, 30% of people thought the flavour should have a blue packet.

On the other hand, 48% of Brits thought Salt and Vinegar should be in a blue packet while 32% favoured green. Despite this being different to how Walkers colours their flavours, the brand has never actually swapped the colours of flavours.

Chris explained that Golden Wonder, the crisp market leader in the UK before Walkers, originally packaged their Cheese and Onion crisps in green and their Salt and Vinegar crisps in blue. Other brands such as Pringles and Hula Hoops also used the same colours.

Chris said this has led to the belief that Walkers had changed their packet colours. However, it was actually the history of Golden Wonder which led to the confusion.

Walkers previously stated: "We're often asked about this! Our Salt & Vinegar and Cheese & Onion flavour crisps packs have always been the colours they are today.

"Contrary to popular belief, we've never swapped the colours around, not even temporarily. We've no plans to change these designs, as they're signature to our brand."

Golden Wonder, founded in 1947, lost popularity due to the rise of Walkers in the 1990s. It also faced challenges such as the fire at its Corby site in 1988 and the sale of key assets like Pot Noodle in the 1990s.

Chris said: "Things have changed. Tesco, Sainsbury's, Asda, Morrisons. The supermarket own brands have all changed to the Walkers colour scheme."

He added: "Supermarkets have shed their old loyalties and gone with the flow. And we didn't even notice."
