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