Can anyone tell me which is the lightest blue of the three? The TWD & Diamine website scans seem to indicate that first one is lighter, then the other.
I've got a bottle of Diamine Turquoise, and like most other Turquoise inks I've come across it's rather dark. I regularly use diluted Pelikan Turquoise (with about 50% boiled water), but that's a little lackluster and, after 15 years, I've got bored with it.
What I really want is a turquoise/light blue that can be photocopied away without destroying the printed text of a document.
Regards
Richard.
