Hello! Are there any colours shapeways does not print? For instance, when you use a normal printer to print on A4 paper, 99% of printers will not print the colour white, instead they just interpret any white areas as something they don't lay ink down on as the paper is already white. Is there any similarities with FCS where it doesn't actually print white (or any other colour) as the material is naturally white or for any other reason? Hope that makes some sense, I just read it back to myself and I'm not 100% it does!
