Acertijo: El misterio del circo

 Imagine: a circus, bright lights, loud music... Three clowns enter the arena! Their names are White, Blue, and Yellow. Each has their own unique look and, of course, costume. The costumes also come in three colors: white, blue, and yellow.

But here's the catch:

"It's amazing," says the White Clown, turning to the clown in the blue suit, "it turns out that none of us have a costume color that matches our nickname!"

The task seems simple, but try to unravel this mystery! You need to figure out which clown is performing in the blue suit. In your answer, simply write the clown's name in the nominative case.

Leave your guesses and explanations in the comments! Maybe you'll be the first to solve this circus mystery!
