Robert Oster Great Southern Ocean is a deep, saturated blue that feels darker and more open-water than tropical. On good paper, reddish sheen can appear over the deepest pools of color.

Independent reviews find only a little shading but a noticeable reddish sheen in heavier applications, with average flow and generally reliable behavior. In normal writing it remains first and foremost a dark blue; the sheen is a secondary reward for wet nibs and ink-friendly paper.
