The most harmonious hue components for the display

This paper proposes a framework of colour preference control to satisfy the consumer’s colour related emotion. A colour harmony algorithm based on two-colour combinations is developed for displaying the images with several complementary colour pairs as the relationship of two-colour combination. The colours of pixels belonging to complementary colour areas in HSV colour space are shifted toward the target hue colours and there is no colour change for the other pixels. The psychophysical experiments are conducted to investigate the optimal model parameters to produce the most pleasant image to the users in the respect of colour emotions. Methods In this study, through the Munsellcolour system developed by human visual experiences, complementary colours are defined which create dynamic emotions and the related areas are established to examine the interactive relationship between the defined complementary colours. The developed methodology shifts the hue component parameters of an input pixel belonging to the complementary colour area toward the most harmonious hue component points based on the complementary two colour pair with respect to colour emotion. The methodology is designed such that there is no colour discontinuity around the complementary colour boundary after the transformation. Results According to the grades of the combination test, more than 30.86% of the judgments revealed that the transformed images are more harmonized than the corresponding original image. This result implies that the users can easily find their harmonized image by adjusting the most harmonious hue components of the developed methodology. General Conclusion The previous studies are oriented toward the influences and preferences of single colours and of memory colours, whereas in this study, by applying colour combination through complementary colour contrast, dynamic emotions can be created from the original images by converting hue components into the most harmonious colour combination.
