LEGO expert Jeremy Moody has spent the past year developing a comprehensive chart of every color present in LEGO bricks. That's 182 shades that Moody has painstakingly arranged and labeled. You can see a larger version of the image here.
Moody includes the metallic tints, translucent pieces, and glow-in-the-dark pieces. It's an indispensable reference guide for LEGO enthusiasts.
