Pilot Blue Black is one of the few standard inks that Pilot makes, other than the higher end Iroshizuku series of course. Pilot Blue Black like most inks named that way is more a grey blue than a black blue. Regardless, it shades well and has a red sheen on the right paper. Pilot Blue Black is affordable, widely available and well known. It’s a great workhorse ink. This is why it has become my ink of choice as a standard review ink for my pens.
