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