Colorized visual aesthetics of interior design based on the VAR model

Color matching is an extremely critical aspect of interior design, and the development of the times has put forward higher requirements for the science of color matching. In this paper, the framework of the structural vector autoregressive model is established by introducing a structural equation in the vector autoregressive model, associating the equation for the lagged value of each endogenous variable and the deterministic time trend term, and solving the equation according to the contemporaneous relationship between data variables. Meanwhile, the structural equation is transformed into the induced form, and the parameters of the SVAR model are estimated using the perturbation terms of the induced form. Then, the underlying principle of color matching effect is analyzed in terms of hue, lightness, and purity based on the SVAR model, and the design is optimized by combining the needs in different scenes. For the home’s interior design, the color matching based on the SVAR model improved the spatial sense effect by 24.05% on average. For office interior design, the SVAR approach improved the emotional expression effect by an average of 18.96%. For commercial interior design, SVAR-based color matching effectively improved coordination by 11.25%. This study helps to break the traditional interior design color application, emphasizes the role of ambiance played by color, and provides an effective addition to the theory of color application in interior design.
