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