Organics Studio created The Masters of Writing Series inks in an attempt to merge a famous writer from previous centuries with a color that brings them to mind. This is the Mark Twain Halley's Comet Blue.  These inks are more unique hues that were made to fill gaps in the available ink world.  This series paid homage with inks such as Jane Austen Violet, Jules Verne Nautilus Blue, Edgar Allan Poe Raven Red, L. Frank Baum Emerald Green, and many others.
