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