Calman Home is a simplified product for supported TVs, using a laptop, colorimeter, and reference video source. Hardware support includes displays, colorimeters, spectroradiometers, and video test-pattern generators from multiple manufacturers. Calman Ready support depends on the display manufacturer and may vary by model. Professional and Home downloads are for Windows, with requirements specifying Windows 7 or later; Patterns for Mac is also listed. The Home Software Bundle costs $449, paid once, and the Professional Software Bundle costs $1,399, paid once. Licenses include one year of updates and technical support.

Little Argyll GUI is an open-source graphical front end for the ArgyllCMS color-management system. Its controls help create and use ArgyllCMS commands for display and printer calibration and profiling, as well as camera and scanner profiling. Saved parameter sets support repeated work. The program can create daylight-series spectrum files with selectable ultraviolet filtering and custom patch sets for grays, near-grays, or tones such as sepia; printer patch sets can include those additions. Documentation links appear throughout the interface. Version 1.0.1 is a Python 3 script with a GTK 3 interface built using PyGObject, and updates Argyll 3.0.0; some parameters are absent in older Argyll versions. Linux, macOS, and Windows instructions are provided. Windows setup uses MSYS2, while macOS setup uses Homebrew. On the maker’s Windows 10 MinGW-w64 system, the background selector does not work. Use requires a color measurement device, such as an i1 Pro 3 or ColorChecker Studio. The listed price is $5 as a one-time purchase payment.
