Your goal is to find the secret four-color code. The following colors are possible: purple, brown, red, white, pink, 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: ['purple', 'purple', 'red', 'pink']. Hint: one color is in the correct position.
