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