I created a pallete file for inkscape
very basic to start with and see if this actually can be usefull
Fritzing Palette
Name: Fritzing
Columns: 8
# generated by ...
0 0 0 #000000 silkscreen
140 140 140 #8C8C8C legs
154 145 108 #9A916C contacts
247 189 19 #F7BD13 copper
255 255 255 #FFFFFF Fritzing white
242 198 00 #F2C600 copper top
242 173 00 #F28A00 copper bottom
15 115 145 #0F7391 Arduino blue
Please let me know what other colours should be in there and their respective values
and I’ll add them to this list.
If you want to try it, copy and paste above codes into a textfile and name it ‘fritzing.gpl’
Put the file in the inkscape pallete folder
Ubuntu users place it in /home/[your user account]/.config/inkscape/palletes
now open inkscape and select the pallete you just created
