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