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.
So we at KiSSFLOW created one for the community. Download the file and import it as a Palette in GIMP and then you are good to go.
##Gimp
####(Tested on 2.8.2)
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.
##Inkscape
####(Tested on 0.48.3.1)
On Linux (Debian 3.2) copy the file Material-Design.gpl into /usr/share/inkscape/palettes/, and then (re)launch inkscape.
