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