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