Different coloured foods depending on allergies is a VERY interesting concept!
Please can someone invent a dairy-free milk alternative that is a DIFFERENT colour to regular milk. The amount of allergic/intolerance reactions this would save would be vast! The no. of times I've asked for almond/oat milk only to be given cows milk by mistake is ridiculous!— Scarlett London (@Scarlett_London) August 6, 2018
