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