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