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