Such an original idea, haven't seen anything like it yet! As an artist I love the challenge of finding the breakdown of RGB values in each color (nice touch with using real-world colors from an existing database). Makes me feel like I'm training to improve my color theory. I wish I can choose to end early if I get a close enough color the first iteration around, as later iterations sometimes get me further and further from the target color. Overall, what an incredible idea, especially for your first game!
