Aesthetic considerations cannot be ignored at a component level and at the final product level. Aesthetics play a very important role in the acceptance of a product. Designers should constantly strive to introduce an element of aesthetics at all levels. This sensitivity rewards well in acceptance of the product at different levels. The sense of aesthetics can be felt at a simple joint level to overall product appearance. Right product conception is the beginning of aesthetic appeal. Simplicity adds to aesthetic appeal. Application of tolerances adds to aesthetics. Application of right surface finishes adds to aesthetics. Ultimately, workmanship adds to aesthetics. On the other hand, overdone aesthetic treatment can have a repulsing effect too.

When there are two machines working in tandem on the shop floor, it will be good to consider giving a family identity. The identity may be with similar shapes and colour schemes. This kind of treatment adds to the attraction. Each area of product application has its own demand for colours and finishes to appeal to the the end-user. The subject of colour and its applications are so vast it is better to consult specialists in taking a decision. In industrial products, however, certain colour standards are established to be neutral and not to distract the operator in stressful work environments.
