Colora
What it is
Colora is a free color converter and screen color picker for Windows. It lets users select colors from the display, save them, and convert them among RGB, HEX, HSB, HSL, and CMYK formats. The screen picker has zoom for more precise selection, and an automatic history keeps recently picked colors available. Users can also make custom palettes, save them for later, and export palettes to GIMP.
For a compact workspace, Colora can stay pinned above other windows and has a minimal size mode. It requires Windows 7 or newer and .NET Framework 4.6 or higher. The maker says the picker has been tested with Windows 10 and DPI scaling. Colora is published by Bluegrams under the BSD 3-Clause license, making it free and open-source software. Downloads are offered through SourceForge, with installation also available through Chocolatey. The maker directs users to SourceForge discussions for general help and GitHub issues for bugs and feature requests. Colora is a desktop utility for selecting and organizing screen colors; its listed tools include print color support, but it does not extract colors from images or provide accessibility checks.
