We have been loving the color palette that Google has prescribed for its Material Design language. However we realized that we couldn't find a readymade palette that we can use in GIMP / Inkscape / Gravit Designer.
This is a fork from the KiSSFLOW. I converted the GIMP palette to a Gravit Designer (.gvswatch) one.
The GIMP version is also compatible with the ColorZilla extension.
Open Gravit Designer and create a document, to go to the Page Color property and select Import Swatch. :)
Open the Palettes window with: Windows > Dockable Dialogs > Palettes. Once opened, click on configure this tab on the top right corner of the new window and select Palettes Menu > Import Palette.... Select the option Palette file and choose the downloaded file Material-Design.gpl.
On Linux (Debian 3.2) copy the file Material-Design.gpl into /usr/share/inkscape/palettes/, and then (re)launch Inkscape.
