Meet New Simple App to Extract Color from Image in Linux

Want to extract color palette from your photo image? There’s a stupid simple app to do the trick in Linux!

It’s “Paleta“, a free and open-source app written Python programming language. It uses GTK4 plus LibAdwaita toolkit for a modern look user interface that works in Linux desktop and even mobile devices, such as PinePhone.

Just open or drag & drop your image into app window, it then automatically extract colors with button to save palette for later use. Or, use can copy color to clipboard with a little button right after each color.

The app uses color-thief as backend, meaning an internet connection is required to do extracting process. As you can see in the screenshot above, user can specify max amount of colors to retrieve. And it allows to set palette accuracy between ‘Precise’, ‘Normal’, and ‘Low’.

All saved color palettes are available under ‘Palettes’ tab. User can edit them and of course add new color palette manually via built-in color picker.

The app is still in early development staging. Meaning there will be new features and also bugs! As a GTK4 app, it looks native and modern in Ubuntu, Fedora, and other Linux with GNOME. And, it follow system color scheme by automatically switching between light and dark mode.
