Blue denotes social standing. According to local legend, the Brahmin community (India's priestly caste) painted their houses blue to distinguish themselves from lower-caste communities, and blue has since been associated with the Brahmins. Today, many other classes of people also live in Jodhpur, including Brahmins who have adopted other customs, so the tradition is now only found among the city's large population of Rajasthani people. In addition to being a sign of status, house painting is also used to indicate alliance or friendship between families, or even as a way for parents to get back at children. If someone paints his/her house yellow, it means that they are happy with their color choice or that they are suffering from jaundice. If a house is painted red, this usually indicates that there is some kind of conflict between its owner and another family member or friend. Red is also used to mark the boundary line of a property; if there are no fences or walls, then workers will often paint one house red to indicate that it is not part of the property next door. Finally, if a house is completely covered in blue tiles, this means that it is haunted. The story goes that ghosts cannot see colors, so when they walk around inside a house they will always find any open windows or doors painted blue to warn people away from living there.
