Looking for a color picker tool for Linux? Try Eyedropper, a new GTK4 application that looks native in modern GNOME desktop.
It’s a free and open-source tool written in Rust programming language. Which, provides an easy to use interface to pick a color and display in HEX, RGB, HSV, HSL, CMYK, XYZ and CIE-Lab formats, as well as handy “Copy to clipboard” icons to quickly copy the values.
User can either use the header-bar picker icon, or click on color bar to open the template for choosing colors. And, edit color by changing the HEX value.
The preferences dialog has options to toggle which color values to display. By setting “Alpha-Value-Position”, it can enable the alpha channel (opacity of a color). However, it’s only available by editing the HEX value so far.
Depends on Alpha-Value-Position option you set, either the first 2 or last 2 values in HEX code applies the color opacity. Though, the alpha channel so far does not work for other color formats!
