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