I need a small tool to ‘pick’ a colour anywhere on the screen (so that I basically get the hex code for it). Earlier, I've used KDE's KColorChooser for this.
According to this page, "Gpick" sounds like what I want, but:
$ apt-cache search gpick
<returns nothing>
Any recommendations?
That's strange that you couldn't install gpick, as I get the following :
apt-cache search gpick
gpick - advanced GTK+ color picker
I suppose it could be in a source that you currently don't have enabled..
To pick a colour, launch Gpick, lcick on the swatch, and then press space when your mouse hovers over the colour you want to record.
(not anymore available in Ubuntu 19.04+)
That being said for simple colour picking I prefer gcolor2 - Nice and simple to use and should do exactly what you require.
You can install it with following command:
sudo apt-get install gcolor2
gcolor2 is not on the Ubuntu repositories anymore, and has been replaced with gcolor3.
You can install it with following command:
sudo apt-get install gcolor3
I like to use the software agave. It's a simple software that gives your color combinations, and it has a color picker.
sudo apt-get install agave
Worth give it a try!

grabc is as simple as it can get. Spawns a cursor, outputs color on stdout when you click. Pure Unix way.
$ grabc

To install it, run sudo apt install grabc.
There's a native color picker for HTML5's <input> tag built into all modern browsers (some screenshots).
Enter this in browser's URL bar:
data:text/html,<input type="color" />
and click on the rendered button. Bookmark for later use. Works offline.
(Technically, this is neither a dedicated app, nor GNOME-specific; which might exactly be the point: no install needed)
If it wasn't mention, gcolor2 can also sample color from all over the desktop.
But I got curious about gpick, and tried to install a newer version on Ubuntu 11.04 Natty. So I got:
precise (there's no earlier); installs in natty via GDebi Package Installernatty via GDebi Package Installer (with previous dependency installed)... however, at this point:
$ gpick
gpick: /usr/lib/i386-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by gpick)
Then I tried getting libstdc++6_4.6.3-1ubuntu5_i386.deb and extracting (not installing) it; and using this:
$ LD_LIBRARY_PATH=/home/user/Desktop/libstdc++6_4.6.3-1ubuntu5_i386/usr/lib/i386-linux-gnu gpick
gpick: symbol lookup error: gpick: undefined symbol: g_dbus_object_manager_server_new
... damn, so it needs more dependencies satisfaction (and if one starts messing with libc, one may as well update the OS :) )
Anyways, back to gpicks webpage, there is a link PPA at Launchpad there - so I got gpick_0.2.0-1~ppakarmic1_i386.deb from the PPA Packages ... page. Installed it again via GDebi Package installer (removing the previous, newer one first, with sudo dpkg -r gpick) - and it works! And even if it's not the latest version, I think it looks quite awesome.
Here is the X11 native solution that
Just run xmag. From its man page:
xmag program allows you to magnify portions of an X screen.Another way to get a simple color picker is to install yad (Yet Another Dialog) and run yad --color.
I recommend GPick:
sudo apt-get install gpick
Applications -> Graphics -> GPick
It's got a lot more features than gcolor2 but is still extremely simple to use - click on one of the hex swatches, move your mouse around the screen over the colours you want to pick, then press the space bar to add to your swatch list.
It also has a traditional colour picker (like gcolor2) in the bottom right-hand corner of the window to allow you to pick individual colours with magnification.
The Gnome Shell extension Color Picker provides a picker and a color palette, generated from previously selected colors.

For those who struggle getting eiter gpick or gcolor3 running: it seems neither of those work on Wayland. However, there is an even simpler tool called wl-color-picker that does the job.
