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