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