Element of Design: One element of design that is used is value, which helps create shading texture when needed. This can help a substance seem "popped-out", and can be used to catch people's attentions. Design is important also in creating what can be seen by the naked eye, and what is placed on there can draw different people into seeing the product in their own eyes. Appearance can be appealing or even unappealing, in getting people to be interested & even talk about the design. Designers design something that is either aesthetically pleasing, or would catch a person's attention, and hopefully spread the word around. Examples of value can be shading, different shades of the same color, etc.
Principle of Design: One principle of design is harmony, which can make it feel wholesome or pleasing the a person. This is a very good way to draw people (especially a sect commonly known as perfectionists) to buy the product. The opposite can also be said, as the distortion can also draw people to buy the product. As long as the design appeals to potential buyers, it is worthwhile to use.
