Study On Visual Comfort Of Color Design Of Subway Carriage

In recent years,the rapid development of the urban subway in China brings great convenience for traveling and has more impact on people’s daily life.However,the subway carriage environment has shortcomings such as insufficient lighting,poor airflow capacity,and enclosed space,which increases the requirements of experience design in a subway carriage.Advances in product technology often promote the development of experience.Passengers are not only satisfied with the subway as a convenient and efficient way of transportation but also want a comfortable environment.The design of the atmospheric environment in subway carriage can help to meet the emotional needs of passengers,alleviate the inherent shortcomings of subway space itself,and thus improve the comfortable sensation.Color plays a crucial role in creating an atmosphere.Vision is the main way for people to obtain information in the environment,which is also the most sensitive to color information.Therefore,the visual comfort experience caused by the color in the subway environment will greatly affect the passengers’ feelings during the ride.This paper mainly studies the effect of color design on passengers’ visual comfort.By combining with the process of color perception and comfort evaluation,this paper explores the impact of color perception in the evaluation of visual comfort and constructs a model of visual comfort evaluation based on color perception.Based on the definition and characteristics of visual comfort,the concept of visual quality is introduced to determine the visual comfort.In the research process,we should not only focus on the improvement of physical parameters but also pay attention to the psychological factors that cannot be measured by objective standards.On this basis,the visual comfort research model of subway carriage color is constructed.The color perception experience and visual comfort experience are taken as the main research objects.According to the research on visual experience,the design criteria are inspired to promote the improvement of the design.Through the case analysis method,this paper summarizes and compares the color design methods and the color effects in the subway carriage adopted by the famous subway manufacturers at home and abroad.The study comb out the color design method and limitations of the present domestic subway.Through the interview method to know about the actual design process and the color selection standards.According to the result of the interview and case analysis,it finds that the colordesign of the existing subway carriage in China does not consider the visual comfort of passengers,and seem to lack relative screening criteria.Results of case analysis and interview show that the existing domestic subway carriage color design mainly has three kinds of design methods,and the integral color effect is relatively drab.Design standards and design consciousness about visual comfortable absent during the design process.It proves the practical significance of this study,and also provides samples for a later experiment study plan.Using literature research,this paper collects and sorts out the specific performance of color perception experience and the existing evaluation indexes of visual comfort experience in digital interface color design.The case samples used in the experiment were selected from the existing color design cases of subway cars provided by CRRC zhuzhou electric locomotive co.,ltd.To test the subjective feelings of passengers’ color perception effect and visual comfort.Through correlation analysis,it is proved that the existing evaluation index of visual comfort experience can still be applied in the subway carriage environment.Color perception effect is positively correlated with visual comfort,among which space sense,bright sense,stable sense,uniform illumination,light color coordination,and information environment coordination are closely related.This result can provide a reference for future research and the formulation of design criteria.Through the analysis of specific cases,it is found that when the phase and purity of the facility color are greatly different,the visual comfort of passengers will be reduced,and passengers’ attention and information recognition capability may also be affected to some extent.If the color used in a large area or is on strong contrast,it may cause a more obvious impact on the passenger’s emotional feeling and may cause interference to the visual function.Combining the experimental results with the existing principle of color selection for subway carriages,the principle of color design for subway carriages aiming at visual comfort is deduced.The design cases,with low visual comfort score in the previous experiment,are improved according to the principle and evaluated by the above-mentioned evaluation indexes.The results show that the redesign cases improve in various visual comfort indexes compared with the original cases.The innovation of this paper lies in the study is that the study explores the relationship between color perception effect and visual comfort in a subway carriage from the color perception experience of passengers.According to the case study,the experimental results and existing subway carriage color principle,the principle of color design for subway carriages aiming at visual comfort was summarized.Thisprinciple contains:meeting the basic requirements,color stable expression,meeting riding function requirements,reference to regional culture,the reduction of sharp contrast,the reduction of large area design application,enhancement to the sense of space,maintaining color stability,the light harmonize with the color,the sign system harmonize with environment.The significant of this paper lies in that the visual comfort index of plane color design is transferred to the subway carriage space.The principle of color design for subway carriages aiming at visual comfort was summarized based on the evaluation of the existing subway carriage color design cases,of which the feasibility was verified through the redesign case evaluation.This paper provides an evaluation index for the future study on visual comfort of color design of subway carriage and a direction reference for the formulation of color design criteria.
