The color of your napkin can apparently influence the flavor of your food. According to an article in The Daily Mail,
Napkin brand Tork partnered with Swedish food stylish and chef, Linda Lundgren, who paired dishes with a range of colored napkins. Lundgren claims, for example, that to make a strawberry shortcake taste sweeter you should serve it with a coral-colored napkin. She adds that mustard yellow helps improve the flavor of green dishes, like salads, and it also pairs well with tart flavors like fish and sea food. Also, grey napkins apparently give Mediterranean food a richer taste.
Wow! Fascinating how the brain works.
