Research On The Cognition Of Designer's Colour Matching Process Based On Problem-Solving Theory

With the progress and development of computer science,the research of computer-aided color design has become a hot spot nowadays.Based on the research of the digitization of color basic elements and the user's color Imagery,this paper explores the optimization method of color design scheme generation system to improve the usability of the generated color scheme.Design is an ill-structure problem,which can not be accurately expressed by rigorous mathematical formulas or algorithms.In addition,color design has strong subjectivity,uncertainty and creativity,but the design process is not a disordered black box.Therefore,based on the general method of color design and grounded theory,this paper captures the designer's design behavior through vocal thinking experiment,and gets the oral analysis report through transcription,segmentation,coding and analysis of oral information from the bottom experimental oral and behavioral operation data.In order to derive the cognitive process model of brilliant color,this paper uses the method of recognizing parts,identifies parts with target as unit,excavates the cognitive characteristics of each stage,explores the design strategy and cognitive characteristics of design in the design process.By using the functions of Nvivo tree nodes and free nodes,the cognitive features of each stage are classified and analyzed,and the types and frequency of cognitive features in each stage of design activities are obtained.Fifteen design schemes were investigated and evaluated by questionnaires.By comparing the content,sequence,repetition and time allocation of design activities of good and bad schemes,the differences of design thinking between good and bad schemes were analyzed and the corresponding teaching suggestions of color design were given.
