ColourSpace vs Little Argyll GUI

ColourSpace is display calibration and colour management software for professional film, post-production, broadcast, medical, Pro AV, and home cinema work. It profiles display performance and uses those measurements to generate calibration LUTs. Interactive volumetric 3D graphs help assess measured colour points and their errors; higher license levels support native LUT generation at 1024³ and beyond. The maker lists integrations with displays and video systems including ASUS ProArt, EIZO, BenQ, LG TVs, AJA ColorBox, Lumagen Radiance, and madVR Envy. ColourSpace is a native Windows x64 application. The maker says Mac use is possible through full Windows emulation and describes a native macOS version as in development. ColourSpace ZRO is free for manual calibration and verification, but has no LUT capability, volumetric graphs, or calibration reports. Standard licenses cover one PC, require internet access for activation and periodic checks, and can be moved through up to five deactivation and activation cycles. Pricing is listed from £125.

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.
