To make life easier for users, the atareao team has packaged the color palettes of the jEsuSdA Color Palettes project and add the one corresponding to the RAL colors.

So it can be easier to install the color palettes for GIMP and/or Inkscape via PPA. And they do not interfere with those that are installed by default in Gimp or Inkscape.

1. Open terminal via Ctrl+Alt+T or by searching for “Terminal” from app launcher. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:atareao/atareao

2. Then update and install the color palettes:

sudo apt-get update

sudo apt-get install palettes-extra-for-gimp palettes-extra-for-inkscape

For those who don’t want to add PPA, grab the .deb package for Ubuntu 17.04 from THIS PAGE.

Click install via Ubuntu Software and it works on all current Ubuntu releases.

Uninstall:

The PPA can be removed via Software & Updates utility under Other Software tab. If you want to remove the color palettes from GIMP or Inkscape, simply run command:

sudo apt-get remove palettes-extra-for-gimp palettes-extra-for-inkscape
