A white lie would cause no discord if it were uncovered and offers some benefit to the liar, the hearer, or both. White lies are often used to avoid offense, such as telling someone that you think that their new outfit looks good when you actually think that it is a horrible excuse for an outfit. In this case, the lie is told to avoid the harmful implications and realistic implications of the truth. As a concept, it is largely defined by local custom and cannot be clearly separated from regular lies with any authority. As such, the term may have differing meanings in different cultures. Lies that are harmless but told for no reason are generally not called white lies.
