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