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