Abstract: Conceptual Colour Design (CCD) is a key step in product innovation. And to identify whether colours meet market demands is crucial for making right conceptual design. Thus a new reliability evaluation method of CCD is proposed in this paper. Firstly, a pure reliability evaluation model is presented according to the Euclidean distance between colour design ideas and market demand. Secondly, RS theory is introduced into calculating weights of influencing factors of colour market demand. The process of constructing decision table of colour RS and extracting weights is presented in detail. Thirdly, an integrated reliability model considering the Euclidean distance and weights of influencing factors is given. Finally, a CCD case of dress is analysed using this method. The results show the evaluation method is practical and effective.

Keywords: conceptual design; colour design; reliability evaluation; rough sets; product innovation; colour market demand; dress design.
