Your goal is to find the secret four-color code. The following colors are possible: purple, brown, black, red, orange, 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.

Guess: ['brown', 'purple', 'brown', 'yellow']. Hint: one color is in the correct position.
