The Taccia Sunao-iro Aoguro Blue Black belongs to the Sunao-iro collection, a series of fountain pen inks created to represent essential colours in their purest form.

Developed and manufactured entirely in Japan, Taccia fountain pen inks are inspired by the Japanese appreciation of fundamental colours. Each ink in the Sunao-iro collection aims to recreate the excitement of discovering a colour for the first time, presenting shades that are clear, balanced and faithful to their essence.
Aoguro: The Elegance of Japanese Blue Black
The name Aoguro (青黒) literally means “blue black” in Japanese. It is a classic colour widely used in traditional writing, calligraphy and formal correspondence thanks to its excellent readability and the visual depth it offers compared with pure black ink.
Unlike a conventional black ink, blue black reveals subtle blue undertones when light reflects from the page or where the ink is more heavily concentrated. This characteristic adds richness and complexity without sacrificing the understated elegance required for everyday writing.
Taccia interprets this colour as a balanced and refined blue black that retains the seriousness of a dark ink while adding the character and depth associated with the finest Japanese blue black shades.
Writing Experience
Aoguro provides a smooth and fluid writing experience with a dark tone that is ideal for documents, journals, correspondence, work notebooks and any situation where excellent readability is required.
Its formulation delivers consistent flow and reliable performance across a wide variety of fountain pens. Depending on the paper and nib used, subtle blue undertones and tonal variations may appear, adding visual depth to the writing.
