INK SWAB 207: De Atramentis Hyacinth Posted on September 18, 2015 by Christine (Pentulant) De Atramentis Hyacinth is a such a pretty blue ink that leans a bit toward purple. It’s a scented ink and while I’m open to the idea of scented inks, this one is not for me – it’s a bit to sweet/strong for my tastes.
