[Richard] wanted to create a color profile for his computer monitor, but he wasn’t thrilled with the existing color calibration offerings he found for sale. Color calibration tools can be somewhat costly, but even more troubling to [Richard] was the fact that they are all closed source. Closed hardware and closed software can be a drag, especially when manufacturers drop support for a product, so he set off to design his own open-source monitor calibration tool.

Once his ColorHug sensor is placed against a monitor, it begins sampling colors from the screen, creating an ICC color profile from the data it gathers. The sensor is a Linux-only tool at the moment, but he has created a live CD from which a color profile can be created, then subsequently used in Windows or OSX.

While ColorHug doesn’t sport all the features of its commercial competitors, its color sampling rate is second to none, and since the software is open, anyone is free to implement any sort of functionality they wish.

[Richard] is currently selling finished ColorHug modules to anyone interested in giving them a test drive, but you can always build your own from the plans found at ColorHug’s Github repository.
