Colora vs Grabient

Colora is a free Windows color converter and screen picker for selecting and saving colors. The screen picker includes zoom for more precise selection, and the converter handles RGB, HEX, HSB, HSL and CMYK. You can create custom palettes, save them for later and export them to GIMP; an automatic history also retains recently picked colors. Window controls let Colora stay on top of other windows or use 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. Downloads are offered through SourceForge, with installation also available through Chocolatey. Colora is published by Bluegrams under the BSD 3-Clause license. SourceForge lists version 0.3.1, dated September 11, 2020, as the latest release.

Grabient is a free web-based tool for making CSS gradients and managing palettes. Users can adjust gradient style, angle and steps, then create, save, browse, manage or like palettes. Search accepts descriptive terms such as colors, moods or themes. Exports include CSS, SVG and PNG; palette pages also offer copy options for colors, ShaderToy and JSON. Unauthenticated GET endpoints provide palette JSON, search, ranked palette lists and PNG renders without an API key. A URL seed determines a palette, so repeating the same seed reproduces its colors. Generated or exported gradients may be used for lawful personal and commercial projects under a perpetual, royalty-free license. Some features require an account, available through Google OAuth or email magic links. The documented API and image reads are limited to 300 requests per 10 seconds per IP, and PNG output has size caps. Grabient recommends itself for UI palettes, gradients and backgrounds, not accessibility contrast checks, image palette extraction, exact brand-hex matching or print/CMYK work.
