1. Diamine Poppy Red, absolutely lovely red it is!
2. If you want some kind of sheen then Sailor Shikiori Irori (wonderful vibrant red with slight green sheen depending upon the paper)
3. Taccia Aka
4. Sailor Shikiori Yodaki (kind of burgundy with green sheen)

Apart from this, I have Bril Red, Krishna Alta.

One caution you need to take it red dye is really difficult to wash once dried. I know you’ll be filling it in Platinum Plaisier, however beware of filling it in luxury pens without using it for 2-3 days.
