Your goal is to find the secret four-color code. The following colors are possible: red, blue, pink, white, black, orange.
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', 'orange', 'black', 'pink']. Hint: one color is in the correct position and one color is in the secret code but in the wrong position.
Guess: ['red', 'red', 'blue', 'pink']. Hint: two colors are in the correct positions.
