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