White lie: A minor, polite, or harmless lie, fib.
White has the connotation of being good whereas black has the connotation of being evil. This is indeed somewhat racist but nevertheless it's the way the language evolved.
A white lie can be excused because it does not cause great harm. For instance, if you don't want to see your friend one day, you tell them you aren't feeling well to avoid telling them the truth, that you just don't want to see them that day. The little white lie hurts no one and sometimes avoids hurt feelings.
