Release [Open Source] Color Tools – Free Windows color picker, palette converter and color theory toolkit
galleryHi everyone!
I'd like to share a free, open-source Windows application I've been developing called Color Tools.
I originally made it for my own graphic design work because I wanted an easy way to pick colors and transfer color palettes between different applications. Since then, I've continued adding features and expanding it into a more complete color toolkit.
Some of its features:
- Color picker – Pick colors from anywhere on your screen (Alt + P), or use the color wheel and sliders.
- Palette converter – Import and export ASE, ACO, GPL, Procreate Swatches and Affinity
.afpalettefiles. Native.afpalettesupport is for Affinity 3.0+, but palettes can be converted to ASE for use in older versions. - Palette editor – Create, edit and organize custom color palettes.
- Color harmonies – Generate complementary, analogous, triadic and other color combinations.
- Color theory guide – Explore color meanings, historical associations, moods and suggested uses.
- Contrast checker – Check color contrast ratios and WCAG accessibility ratings.
- Color blindness simulation – Preview colors for different types of color vision deficiency.
The application is currently Windows only. A standalone executable is available in GitHub Releases, so there's no need to install Python.
It's completely free, with no subscriptions or ads, and the source code is available under the MIT license.
