nKolor – Linux Color Picker (GTK4)
nKolor is a Linux color picker built with GTK4, designed for fast and easy color selection. The application has been tested on Linux Mint and is available as an AppImage for simple installation and use.
It allows users to select and manage colors in multiple ways. You can pick colors directly from the screen using a high-precision magnifier (pixel-level selection), or through the built-in HSV picker. It supports multiple color formats such as RGB, HSL, and HSV, with live preview for every change.
In addition, it includes a color history for quick reuse, as well as the ability to find similar colors, helping you create harmonious color palettes with ease.
