Why is Titanium so COLORFUL? - Making/Anodizing Titanium Chopsticks

One of the many reasons titanium is an amazing material is because of the beautiful colors that can be formed on it's surface by either heating it up or using a bit of electricity. But titanium dioxide is just a white powder so how does having a thin layer of it on the metal lead to rainbow colors? The answer not only explains why titanium is colorful, but also why oil films and bubbles look iridescent as well! Today we go through my process for making these stunning chopsticks, and then deep dive into the quantum mechanics that make those colors form.
