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