Features

• Pick a Color
• Enter a color in Hex-Format
• Parse RGB/RGBA/ARGB Hex-Colors
• View colors in formats
• Customize which formats appear as well as their order
• Generate a palette of different shades

Available formats

• Name (includes W3C color sets, GNOME Palette and xkcd color survey)
• Hex
• RGB
• HSL
• HSV
• CMYK
• XYZ
• CIELAB
• HWB
• CIELCh/HCL

When should I use this? And when not?

This application is geared towards advanced users (developers, designers, etc…), who not only need to pick a color but also modify or view it in different formats. For simply picking a color on Gnome, the color-picker extension is far better suited.

Building

See this general guide for building the project using GNOME Builder.

Alternatively use this VS Code Extension for working inside VS Code.

Building manually

Alternatively, it is possible to build the project manually using flatpak-builder. First install the required sdks:

flatpak install org.gnome.Sdk//43 org.freedesktop.Sdk.Extension.rust-stable//22.08 org.gnome.Platform//43

Then build it using:

flatpak-builder --user flatpak_app build-aux/com.github.finefindus.eyedropper.Devel.json

To run it:

flatpak-builder --run flatpak_app build-aux/com.github.finefindus.eyedropper.Devel.json eyedropper

Build without flatpak

meson --prefix=/usr build
ninja -C build
sudo ninja -C build install
