Riddles are always captivating because of the subtle misdirection in word choice. At first glance, this question seems contradictory: clean is usually white, while smudged is associated with dirt. But here, everything seems to be completely reversed : "What is clean but black, and smudged but white?"

This very contradiction confuses many people when they think in a conventional way. If you only stick to the literal meaning of the words, you can easily fall into the trap of the question.

A helpful tip is to think of familiar objects in everyday life, where colors can change depending on how they are used. Sometimes, what seems illogical becomes perfectly logical when viewed from a different perspective.
