blue or black pen?

I use black signature pen for signatures but for notes I use blue pens usually.

Black is better to read, but blue, better to eyes, i use Blue, and sometimes green :P

I think the default is blue so I use blue.
It is not a big deal for me but blue is also my favorite color.

Well i always used blue pen because something written with blue ink is easy to read.

I use pens with blue ink. You can correct mistakes with corrector easy, if you write with pen blue ink( I think, I made mistake here)

I use black and blue pens i dont see differents

I use blue pens, Because they are better for writing anything.
