The functional aspects of many of the consumptive
products used in our daily lives are now fully matured.
Consequently, enterprises seeking to develop new
products are now obliged to place an ever-increasing
emphasis on a product’s apparent style, i.e. its color and
form. However, conventional numerical approaches are
limited in their ability to ascertain an individual’s
psychological reaction to a particular product style. A
mutual dependency exists between a product’s form and
its color when considering the overall image sensation of
the product. Accordingly, a quantitative evaluation
method using gray theory for the CIE color planning stage
of product design is proposed in this paper. Subsequently,
this paper further develops an approach to evaluate the
integrated image of a multi-colored product form based
on the theorems of fuzzy neural networks and gray theory.
Two case studies are taken to demonstrate the
effectiveness of the image evaluation approaches for the
product color design and the multi-colored form design.
