Blue Black
Colorado Pen is one of the 713 brands in Inktend's built-in ink catalog.
Paper & pairing
As a near-neutral tone, it reads as professional and safe for anything from journaling to signatures. This ink will behave predictably on most fountain-pen-friendly paper. Cheap, highly absorbent paper (standard copier paper) will dull any ink's saturation and can cause feathering or bleed-through with wetter nibs.
About Colorado Pen
Colorado Pen is a Colorado-based American retailer of fine writing instruments, selling fountain pens, rollerballs, ballpoints, refills, and inks from premium brands such as Montblanc, Parker, Waterman, and Lamy. The company emphasizes concierge-level customer service and same-day shipping, and has offered exclusive house ink colors named after Colorado and Western landscapes.
Storing and using the bottle
Bottled fountain pen ink has an effectively long shelf life when kept capped and out of direct sunlight: most inks remain usable for years. The main risk isn't the ink spoiling, it's a pen sitting inked and unused for weeks: that's what causes clogs, not the ink's age.
