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