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