From the same batch of ink samples from Ross at Pure Pens that greeted me upon my return from holiday:
Diamine Oxblood – A thick dark rich ink that bleeds easily when added to water and behaves like a watercolour paint with hints of yellow in the lighter wash areas. Only reacts with bleach where the colour has been thinned by water. A deep rich red when used for writing.
Diamine Red Dragon – Very similar qualities to the Oxblood. A thick dark rich ink that bleeds easily when added to water and behaves like a watercolour paint. Only reacts with bleach where the colour has been thinned by water. A deep rich red with a slightly yellower hue than the Oxblood when used for writing.
Diamine Monaco Red – Very similar qualities to the Oxblood. A thick dark rich ink that bleeds easily when added to water and behaves like a watercolour paint. Turns a neon white/gold colour when subjected to bleach. A deep rich red with slightly more yellow than the Red Dragon when used for writing.
Diamine Ancient Copper – Wow! A thick dark rich ink that bleeds easily when added to water and behaves like a watercolour paint with hints of yellow in the lighter wash areas. Turns a yellow gold when subjected to bleach. A gorgeous chestnut colour when used for writing.
Diamine Autumn Oak – A beautiful tan coloured ink that bleeds easily when added to water and behaves like a watercolour paint with hints of yellow in the lighter wash areas. Turns a neon yellow gold when subjected to bleach. A gorgeous autumn brown colour when used for writing.
Diamine Golden Brown – A deep dark umber ink that bleeds okay when added to water and behaves like a watercolour paint. Turns a neon white/gold colour when subjected to bleach. A mid brown colour when used for writing.
I have used a heavy Bockingford watercolour paper with a rough texture.
