Color Grabber vs DisplayCAL

Color Grabber is a Windows utility that copies the color beneath the cursor to the clipboard in a configured format. Hexadecimal is the default, and CSS rgb[a] is also available. It can copy a paint swatch rather than a color string; the default swatch size is 64. A system crosshair cursor can be used for pixel-accurate selection in the two-step selection process. When clipboard watching is enabled, the window updates to show valid colors found on the clipboard. The preview targets four frames per second by default, and visible color notifications are enabled by default. Color Grabber is included in the Color Grabber, Capture and Clipboard Utilities, Simplode Suite Complete, and Simplode Free Select packages. The free Simplode Free Select option costs nothing and allows one premium feature or feature set at a time; the selection can change once every 24 hours. The download page describes a 24-hour premium-feature trial that can be renewed up to three times. Simplode Suite supports Windows 10 and may partially work on older Windows versions. The maker describes its download as around 10 megabytes.

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.
