We've posted about the Nix Mini Color Sensor before: a pocket-sized device that will tell you the color of any physical object. If you've ever struggled to match the color of a real-world object to the color of a digital object (or vice-versa), then you'll quickly realize just how revolutionary this tool is. Nix has recently released a new and improved version – the Nix Pro Color Sensor – that takes everything that was great about the Nix Mini Color Sensor and adds several game-changing new features. While the original Nix limited you to a handful of pre-existing color libraries, the Nix Pro lets you import your own custom color libraries and use those for color matching. Whether you're a lab professional, a color consultant, or just an all-purpose color nerd, this will significantly improve your color game.
