Thread color palettes
Ink/Stitch comes with many thread manufacturer color palettes which can be installed into Inkscape. This allows to build the designs with the correct colors in mind. Colors will appear in the PDF-Output and will also be included into your embroidery file, if your file format supports color representations.
