From afar, it will be assumed that anyone wearing a Dumalla (large turban) is an Amritdhari (initiated Sikh) since it is usually Amritdharis who will wear it. For this reason, it is important for anyone wearing a Dumalla to strive to upkeep the overall lifestyle qualities associated with an Amritdhari - even if they are still on their way to Amrit (nectar of immortality). For Sikh identification purposes, Dumalla colours include yellow/orange, black, white and blue. This is so that from afar, you can tell the person is a Sikh. These colours do not have a particular spiritual significance.
