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