Why are there such diverse color choices within a country or region throughout the world? The most obvious reason is the dominant cultural influences present in that area. Each culture adds traditional patterns and designs and the colors associated with them into the mix. We see these motifs repeated in fashion for clothing as well as home furnishings and sometimes it is carried to exterior color choices as well.
Another strong influence is the climate in a particular area. We see dominate warm colors in warm climates and cool colors in cool climates. For example, the colors of the tropical flowers abound in areas where these exotic flowers are prevalent. Where rain and cold are common, we see the cooler grays and blues in residences.
A third explanation is the use of a common available substrate such as wood, stone or other building materials. For example the use of cedar is common in areas where it is readily available; you do not see it as much in deserts where stucco is more customary. Colors associated with these materials then become commonplace in those regions.
Other influences include historic styles found in older, established cities or simple country looks in rural areas. Many styles are carried from one part of a country to another and from one country to another. There are many areas in North America that have regions settled by ethnic groups from another country. For example the Dutch settled in New York, the French have a strong influence in eastern Canada, the Asians on the west coast, and the Spanish in southern and western states. The central plains of North America are a mix of many different European countries such as Ireland, Scotland and Germany. Each of these groups left their mark on the landscape with Tudor, French Colonial, Georgian and Mission styles scattered across the continent.
It is no wonder that single regions in North America have a broad mix of cultures and styles unlike their European, Asian and foreign counterparts. The immigrant settled North American landscape is definitely a melting pot, not only for its ethnic mix but also for its broad range of styles and colors. That is not to say that they don’t have a predominate style or color set, but that even that is unique to the region.
