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