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