A Field Guide to Color: Beyond RGB

Color rocks. Because color is so fundamental to how we process visual information, data visualization often relies on color for communicating information. (This isn't just graphs: traffic lights change color to help you know when to hit the gas, for example.) There are a surprising amount of difficulties that arise when trying to use color in the most accurate way possible. Let's investigate those, on a quest to create an optimal set of colors for data visualization.
