Your goal is to find the secret four-color code. The following colors are possible: white, red, orange, green, brown, black.
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: ['white', 'red', 'white', 'green']. Hint: two colors are in the secret code but in the wrong positions.
