Colora vs ColorPalette Pro

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.

ColorPalette Pro is a web app for generating customizable color palettes from a base color. It creates analogous, complementary, split complementary, triadic, tetradic, and tint-and-shade palettes, with square, triangle, circle, and diamond variations for each type. Colors can be entered as text, adjusted with sliders, selected with an eyedropper, recalled from history, chosen at random, or supplied through a URL. Supported color spaces include OKLCH, LAB, LCH, HSL, and RGB. UI mode generates interface palettes with surface and on-surface colors, including light and dark versions. Palette values can be copied as CSS, saved as a CSS file, or rendered as an image; a URL can preserve the chosen color and most options for sharing. Palette images can be dragged into Figma for sampling. The app matches color names through an API using hex values and uses Color.js for color-science functions. It is open source under the MIT license, and its maker says there are no plans for ads or subscriptions. The eyedropper is unavailable in Firefox and mobile browsers.
