While you may think ‘Orange’ is the only color that has no rhyming words, there is actually a second. Purple is another entry on the long list of English words that have no perfect rhyme. A perfect rhyme is a word that rhymes perfectly with another word, as opposed to an imperfect rhyme, which can sound like it almost rhymes but does not actually. Purple has no perfect rhymes and only a very select few imperfect rhymes. For example, the word ‘turtle’ sounds like it almost rhymes with purple, but it is an imperfect rhyme.
