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