Why only blue in the traditional architecture of western Himalaya,India?

The local environment defines the traditional designs and color of buildings in remote wilderness areas. Color, an integral element of the traditional architecture, is related to the culture, experience, perception, and beliefs, which forms a part of the traditional knowledge of the user. Some ethnic groups have been using some specific color patterns in their houses for generations, which have been carried forward in their traditions and customs. Recognizing this, a study to document the color preference and motivations for the preference of specific colors by an ethnic community residing in the interior valleys of western Himalaya was conducted. By group discussions, 13 indicators, which further merged into five motivation categories, were identified. Semistructured interviews (n = 159) were conducted to assess the perception of selected ethnic groups toward color preference. This study reveals that color preference in architecture is influenced by psychological and sociocultural reasons that vary with gender and age classes.
