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