History for ColorVerse Project - Constellations 013 α Uma

ColorVerse "Project - Constellations" no. 013 α Uma (Alpha Ursae Majoris, the star "Dubhe", second-brightest star of Ursa Major) is technically a medium grey ink. It contains elements of yellow and purple, but can look green or pinkish depending on amount and paper. It dries fast, but opinions differ on whether it is dry or wet in flow. It appears it may feather, or be crisp, perhaps depending on batch. There is some shading, but it could be pale on some papers.
It is sold in a uniquely shaped glass bottle, round but with a small "tail" like a comet, that holds 65 ml.
