Waterman Serenity Blue (formerly known as Florida Blue): A standard blue ink of medium saturation, Waterman Serenity Blue will not wow, like more showy blues, but it is a workhorse that has stood the test of time. Washable, not water-resistant.
An everyday ink? Yes.
(Here begins an occasional exercise, the brief review. I got the idea from a friend who thinks that most reviews could be four sentences or less. While I naturally gravitate to Dickensian length, I thought it would be fun to try.)
Fountain Pen Follies 
You know, I don’t. Pelikan Royal Blue is the only one I know for sure that works with an ink eradicator. The Waterman is washable, like Parker Quink Blue. In fact, at one point Waterman called it “Washable Blue.” I’ve seen the old ink bottles.
