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