Koreans used to favor the color white for their clothing. However, according to the season or a person's status in society, the color, material and manner of wearing the clothes varied.
For special ceremonies such as weddings, commoners could wear colorful clothing and ornaments, otherwise reserved for the upper class and royalty.
