Paper & pairing
Blues and navies are the most broadly "safe" fountain pen colors: legible, professional, and unlikely to raise eyebrows in an office. 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 Kingdom Note
Kingdom Note is a specialty writing-instrument shop in Nishi-Shinjuku, Tokyo, offering more than a thousand new and used pens with a focus on fountain pens. The store commissions its own original ink colors, which are manufactured by Sailor, and its limited-edition inks, often themed around Japanese nature such as mushrooms, insects and birds, are highly sought after by collectors.
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.
