ColourSpace vs QuickGamma

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.

QuickGamma is a Windows utility for adjusting monitor gamma without expensive calibration hardware. It can correct gamma to 2.2 and create an ICC profile with a VCGT tag containing data used to load a graphics card’s lookup table (LUT). QuickProfileLoader is installed automatically with the utility and can load a monitor’s LUT from that profile data. The listed capabilities also include LUT calibration, ICC profile export and multi-monitor calibration. Version 4.1.0.0 requires Windows 10 or higher; its installation file includes 32-bit and 64-bit versions, help files and no runtime libraries. QuickGamma is free for personal use, while commercial use requires written consent from the author. Private users may distribute the complete, unaltered installer, but not individual components. The author offers no express or implied warranties and invites donations. A SHA-512 checksum is published for checking downloaded file integrity. The maker also lists utilities for reading LUT and VCGT data and creating monitor ICC profiles.
