Abstract: In products industry,color scheme design generally relies on designers' experience and plenty of experiments.An intelligent color scheme design method is proposed in this paper.The method is based on color semantic and interactive genetic algorithm.Firstly,the semantic of color groups are obtained by analyzing the semantic data from user investigations by using fuzzy theory.Then,the semantic of each single color is extracted from the sampling color groups by using factor analysis.Given a combination of semantic words,a color scheme can be designed and optimized with the interactive genetic algorithm.In this processing,the scheme fitness is computed with the color semantic,color harmony and user's evaluation.The scheme fitness has an increasing tendency.In color harmony computing,the influence of dyed fields is considered.An appropriate resulting scheme can be gotten with a small number of iterations.Experimental results show that the method provides a potential approach for product color scheme design.
