\"\"<\/a><\/p>\n

Looking for a color picker tool for Linux? Try Eyedropper, a new GTK4 application that looks native in modern GNOME desktop.<\/p>\n

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<\/b>, RGB<\/b>, HSV<\/b>, HSL<\/b>, CMYK<\/b>, XYZ<\/b> and CIE-Lab<\/b> formats, as well as handy “Copy to clipboard” icons to quickly copy the values.<\/p>\n

\"\"<\/a><\/p>\n

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.<\/p>\n

\"\"<\/a><\/p>\n

The preferences dialog has options to toggle which color values to display. By setting “Alpha-Value-Position”, it can enable the alpha channel<\/b> (opacity of a color). However, it’s only available by editing the HEX value so far.<\/p>\n

\"\"<\/a><\/p>\n

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!<\/p>\n
