Just as every human has a different identity, so also each color has its own different identity. Sometimes things are differentiated by color too. As you said in the post, white color has been given as a symbol of peace. Red color is good from a distance because it looks good only in fire safety equipment. Red color for a car is very thought provoking. People here prefer black cars. Now in the summer time, the sun is so hot here that if the car falls in the sun, it becomes an oven. So I keep the black color away. White color is superior in every way. @galenkp
