The MudPack series is mysterious and dark. Like gems, hidden from view but revealed only to a few. So named denoting the dark and sometimes cloudy appearance of the colors when dry on your papers. Eminently suited to writing as much as to ink art applications.
Muddy Crown. A striking violet-blue. Able to exhibit a remarkable bronze sheen.
