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