Gcolor3: a color selection dialog written in GTK+ 3
Ever wanted to know the value of that color on your screen? Gcolor3 enables you to pick the color from any pixel on your screen. It also offers a palette, so that you can easily mix and match a couple of colors together.
When you have found the perfect combination of colors, naturally you want to save them. Gcolor3 allows you to conveniently save and retrieve colors.
Gcolor3 does not work on Wayland (see issue #38).
To be able to install apps from Flathub you need to add the Flathub remote server:
$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
Now you can install Gcolor3 with the following command:
$ flatpak install flathub nl.hjdskes.gcolor3
To run Gcolor3, use:
$ flatpak run nl.hjdskes.gcolor3
Gcolor3 is packaged for some Linux distributions:

openSUSE: There is an openSUSE package available.
Ubuntu: There is a PPA available.
Compile from source
To compile Gcolor3, you need the GTK+ 3 development packages and your Linux distribution’s package containing the tools to compile packages.
When the build- and runtime dependencies of Gcolor3 have been installed, run the following commands to build and install Gcolor3:
$ meson build $ ninja -C build # ninja -C build install
Optionally, the development packages can now be uninstalled.
