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