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