gpick
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.
gcolor2
(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
gcolor3
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
