This time it's a story.
Talk about the psychological effects of color.
Depending on the color, the image of taste given to people is different. (Pink is sweet, yellow is sour, etc.)
There are cooking methods that trick the brain by adding color rather than adding flavor directly, such as food coloring or paprika powder (a red powder that doesn't have much flavor or aroma).
Many of the images of scents are intuitive.
Coloring is very important, especially in Japanese cuisine, as there is a culture of enjoying food with the eyes.
