I've long wanted to make this comparison but only recently found a pen in which it came out as I thought it should, a Lamy Studio in extra fine.
Row 1: Ama Iro, Kon Peki, Équinoxe 6, Souten, Tsuyu Kusa, Asa Gao, Myosotis.
Row 2: Chiku Rin, Vert Empire, Verde Muschiato, Ina Ho, Lie de Thé, Yama Guri, Perle Noire, Perle Noire.
Row 3: Mandarin, Fuyu Gaki, Orange Indien, Ancient Copper, Rouge Hematite, Poppy Red, Verdigris, Inti.
I really like this ink but for some reason it doesn't look good next to just any others, it seems fine next to browns or other purplish blues. It also looks very close to the ink used on grids, lines and séyès by Rhodia and Clairefontaine. It looks awful to me with yellow lighting.
In this picture they all look quite accurate, poppy red and Yama Guri are coming out darker than usual, Équinoxe 6 is doing its initial impression of a purplish blue but a few paragraphs later veers towards a greenish blue.
Paper: Rhodia n. 8 pad.
