An approach for façade colour design A model for the assessment of façade colour perception parameters A screen experiment about façade colour perceptionA model has been proposed to evaluate the parameters of building facade colour perception under fixed conditions in a virtual environment and a screen experiment has been carried out in this direction. In the results obtained from the screen experiment, it was understood that the inherent colour-perceived colour differences are greater than the discrimination thresholds given in the literature for the Munsell Colour System components of the human visual organ. Figure A. Visuals of the preparations and results of the screen experiment Purpose: The purpose of this study is to determine parameters affecting the façade colour perception. In accordance with this purpose a model has been developed about façade colour perception and a screen experiment has been carried out to specify the degree of change in façade colours under different circumstances. Theory and Methods:The method of the model, which was developed with the assumption that the sky conditions, the view distance and the surrounding colours change the perceived colour of the building facade, consists of three basic steps. These are, creating schematic visuals containing visual perception parameters, showing visuals to colourtrained subjects in a virtual environment and evaluation of the subjects' responses to the visuals. Results:As a result of the screen experiment, it has been observed that among the criteria affecting colour perception, the sky condition and view distance affect the value and chroma component of the perceived colour of the blue building facades. Besides surrounding colours affect the hue component of the red building and the value, chroma component of the blue building facades. Conclusion:Despite the perceived colour changes obtained from the screen experiment result, it can be said that the inherent colour-perceived colour separations for the components do not create significant changes in terms of colour contrast arrangements. Also, the result of this study and comparison of results with other studies showed that more research on façade colour perception are needed depending on different colour perception parameters.
