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