ColorThink vs DisplayCAL

ColorThink is a color graphing and analytics tool for calibrating printing systems, checking accuracy, and preparing measurements for ICC profiling or color references. ColorThink 4 measures directly from connected instruments and sends results to a worksheet or graph. Color Assets organizes installed profiles and other color assets, with metadata filtering and sorting. Pro licensing adds gamut comparison by subtraction or addition and calculates a Gamut Comparison Index. Image animation is available across license levels, showing transitions between normal display and Lab color values in the grapher. PrePressPack adds nColor and color-list handling, device-link and ColorCast profile creation, white-point editing and remapping, and patch tuning. Listed instruments span X-Rite, Barbieri, Konica Minolta, Techkon, and Color Sentinel. The software runs on macOS and Windows; version 4.2 is listed for both. Photo licensing starts at $249, paid once.

DisplayCAL is a free display calibration and profiling solution built on ArgyllCMS, available for Linux, macOS, and Windows. With a supported measurement instrument, it measures displays and creates calibrations and ICC profiles, including for multi-display setups. Users can verify profiles and display devices, measure screen uniformity, and create video 3D LUTs with optional CIECAM02 gamut mapping. Colorimeter corrections can be imported from vendor software or created from measurements when a spectrometer is available. A test chart editor makes patch charts and accepts pasted data from CGATS, tab-delimited CSV, and spreadsheet applications. Documented pattern generators include madVR and DaVinci Resolve 10.1 or later; Chromecast support is optional. DisplayCAL requires ArgyllCMS 1.0 or newer and a supported measurement instrument. The software is licensed under GNU GPL version 3 or later and comes without warranty.
