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