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