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