Colora
What it is
Colora is a free Windows color converter and screen picker for selecting and saving colors. The picker includes zoom, and the converter handles RGB, HEX, HSB, HSL, and CMYK. Users can create palettes, save them for later, and export them to GIMP. An automatic history retains recently picked colors. The window can be pinned above other windows or reduced to a minimal size. Colora requires Windows 7 or newer and .NET Framework 4.6 or higher. The maker says the picker is tested with Windows 10 and DPI scaling. Downloads are offered through SourceForge, with installation also available through Chocolatey. For general help, the maker points users to SourceForge discussions; bugs and feature requests can be raised through GitHub issues. Bluegrams publishes Colora under the BSD 3-Clause license. SourceForge lists version 0.3.1, dated September 11, 2020, as the latest release.
