Paper & pairing
Blues and navies are the most broadly "safe" fountain pen colors: legible, professional, and unlikely to raise eyebrows in an office. Sheening inks need the right conditions to show off: a wetter nib and a coated, less-absorbent paper (Tomoe River and similar sheets are the community standard) let the ink pool slightly and separate into its second color as it dries. On cheaper, more absorbent paper the sheen effect will mostly disappear.

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.
