Diamine China Blue – Bleeds okay when added to water. Turns a beautiful gold colour when subjected to bleach. A lovely rich true blue ink when used for writing.
Diamine Royal Blue – Bleeds easily when added to water with cyan and pink traces in the bleed area. Turns a white when subjected to bleach. A lovely rich blue blue ink when used for writing with a very slight pinkness.
Diamine Beau Blue – Bleeds easily when added to water. Turns a neon white/gold colour when subjected to bleach. A lovely rich cyan blue ink when used for writing.
Of all the Diamines I have experimented with this far, these are quite flat. I have no doubt that they are great writing inks but I’m looking for personality and surprises – and there’s not a lot here.
