Your goal is to find the secret four-color code. The following colors are possible: red, brown, yellow, white, blue, 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: ['red', 'red', 'yellow', 'white']. Hint: one color is in the correct position.
