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