Your goal is to find the secret four-color code. The following colors are possible: purple, white, yellow, pink, blue, red.
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: ['purple', 'blue', 'red', 'yellow']. Hint: two colors are in the secret code but in the wrong positions.
Guess: ['white', 'purple', 'white', 'red']. Hint: one color is in the correct position and one color is in the secret code but in the wrong position.
Guess: ['white', 'white', 'blue', 'pink']. Hint: three colors are in the correct positions.
