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