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