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