Your goal is to find the secret four-color code. The following colors are possible: red, brown, blue, green, purple, 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: ['yellow', 'purple', 'red', 'green']. Hint: two colors are in the correct positions and one color is in the secret code but in the wrong positions.
Guess: ['red', 'red', 'brown', 'green']. Hint: one color is in the correct position and one color is in the secret code but in the wrong position.
Guess: ['red', 'red', 'red', 'blue']. Hint: none of the guessed colors are present in the secret code.
