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