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