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