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