The ColorHug is an open source display colorimeter. It allows you to calibrate your screen so it can display accurate colors. By buying OpenHardware like the ColorHug you can be sure you are supporting an ecosystem of people who want to create open source products that are even better than their proprietary counterparts. ColorHug2 was built as an upgrade to the original ColorHug device that was only capable of profiling some types of display.

The XYZ color values measured using the ColorHug are processed into a ICC file which can be used in Windows, OS X and Linux. The supplied LiveUSB disk contains all the required software, or you can use your existing Linux installation.
