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