This little tool has been around for at least a decade, but it suddenly appears to be missing. It's in debian stable, so I figured it would get inherited. Does anyone know if it was intentionally removed, and if so where I can learn more?
It is not too difficult to install it manually (from 16.04 LTS xenial repository):
cd ~/Downloads wget http://mirrors.kernel.org/ubuntu/pool/universe/g/gcolor2/gcolor2_0.4-2.1ubuntu1_amd64.deb sudo apt-get install ./gcolor2_0.4-2.1ubuntu1_amd64.deb
And then use it as before:
1. modern alternative -
gcolor3 is packaged in very few distributions.
(see at repology.org).
2. on Ubuntu
gcolor3 is installable from
gcolor3 does not have broad list of predefined colors (see above, reported bug 110 to developer).
4. another alternative is KColorChooser, it is installable from repository as
kcolorchooser package, but it does not have list of named colors.
zenity --color-selection provides a no-frills color-dialog. In 19.04, but not in 18.04, the "dropper" in the top-left corner allows you to click on any item on your desktop.:
There's also yad which is said to offer more features than zenity. And the version in 18.04 comes with a dropper to allow you to pick a color from any item on the desktop:
If you would care about a gcolor2 alternative, I am recommending Gpick.
It's easy to use and has a lot of features, which you can find in Gpick's website. You can install it by running:
sudo apt install gpick
