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