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