Vivid Blue
Sumire is very much in the same line as Sky High or Souten, but unlike those two, which are all but identical, Sumire is noticeably different. It’s significantly more vivid, a very bright blue closest to Kon Peki or Diamine Mediterranean Blue, though it’s not an exact match for either. It’s absolutely gorgeous and quite easily readable but can be a bit bright to read whole pages of, if you’re sensitive to that. It does sheen with the classic pink/red sheen found in Souten and Sky High, but less so- more like the level of sheen in Kon Peki, which allows the base color to really show well. It’s a bit less syrupy-smooth than some Sailors, also. Still a very smooth, well-flowing ink, just not quite as cushiony. Again, more like a Pilot Iroshizuku line ink. A fantastic ink.
