Your goal is to find the secret four-color code. The following colors are possible: brown, yellow, black, purple, pink, white.
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: ['brown', 'yellow', 'yellow', 'white']. Hint: two colors are in the correct positions.
