A quick look at four blue inks from Diamine.

 Diamine Midnight  (strange that this image is bigger than the others, right?)

  Diamine Presidential Blue

  Diamine Registrar’s Blue Black

  Diamine Denim

Which do you love?

I’m not sure that I have a favorite, but I definitely have a least favorite – Diamine Registrar’s Blue Black. It’s not very well saturated – looks more like a gray/grey – and I just don’t like it. Not one little bit.
