Your goal is to find the secret four-color code. The following colors are possible: black, purple, white, yellow, pink, blue.
Some guesses have already been made. I will provide feedback for each guess made with which it is possible to unambigiously determine the secret code.

Previous Guesses:
Guess: ['white', 'black', 'blue', 'yellow']. Hint: one color is in the correct position and one color is in the secret code but in the wrong position.
Guess: ['black', 'black', 'purple', 'yellow']. Hint: three colors are in the correct positions.
Guess: ['white', 'purple', 'yellow', 'yellow']. Hint: one color is in the correct position and one color is in the secret code but in the wrong position.
