Study On Color Matching Design In The Living Space Of 24-hour Care Facilities For The Aged Under The Concept Of Healing Environment

In recent years,with the acceleration of the aging process of China's population and the increasing demand for institutional pension,the living space of 24-hour care facilities for the aged has attracted more people's attention.As the core area with the highest frequency of use for the elderly,the living space is the important content of creating comfortable 24-hour care facilities for the aged.Studies show that about 80 percent of the information people get from the environment comes from vision,and the visual organs of the elderly are the most sensitive to color stimuli.At present,the color research of 24-hour care facilities for the aged is not in-depth enough,and there is a lack of visual comfort,color properties,and the psychological and physiological changes of the elderly.This paper attempts to explore a quantitative and qualitative color design method based on the concept of healing environment by analyzing the psychological state and physiological characteristics of the elderly after they move into the 24-hour care facilities for the aged,as well as the therapeutic effect of color environment in the living on the physical and mental health of the elderly.Of Harbin,this study selected 24-hour care facilities for the aged as the research object,research,analyze the present situation of the 24-hour care facilities for the aged in the living space color through the analysis of the psychological characteristics and physiological characteristics of the elderly,the elderly in the healing and the physical and mental characteristics related to comb the elderly demand for 24-hour care facilities healing space environment,establish a therapeutic color design strategy of space environment.The main research methods are questionnaire survey,interview,photo taking,NCS colorimetric card color collection and computer-aided data analysis.Based on the color data obtained from the survey,the semantic evaluation of the monochromatic color samples by the elderly was obtained by combining the semantic difference method.Then,according to the principle of gray clustering,this paper analyzes the overall semantic tendency of color collocation and constructs a feasible color database.Finally,according to the beauty of color matching and harmony of color matching,the evaluation function of visual comfort is constructed,and the color matching scheme with the highest fitness is obtained by using the genetic algorithm.The relationship between visual comfort and three attributes of color,namely hue,lightness and purity threshold,in the living space of 24-hour care facilities for the aged is analyzed.Through the assessment of the health status of the elderly subjects,the therapeutic potential of the experimental environment was indirectly inferred,and the color matching scheme proposed in this paper was proved to have better therapeutic properties.Healthy living space is the foundation of the elderly happy,along with the social from all walks of life pay more and more attention to the elderly healthy living environment,this paper aims at the elderly living colour healing space building designers to provide a reference,and help the 24-hour care facilities for the aged are optimized by the colour more healing effect of the living environment.
