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