Abstract
Recently, we can see many sorts of confection’s package designs at not only the mom-and-pop candy stores but also the modern commercial facility like convenience store or supermarket. The package design of confections is “updating” day by day, however, some confections save original design from when it was on sale. Wondering why they can keep selling the products longtime, I made a hypothesis there are any design methods to be long-seller products in the package design. Taking an example “Bontaname” and calculated its ratios of the color areas of background color and the color of motif. As a result, it keeps same ratio in its each standard.
