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