Has anyone had the experience of mixing Pilot Iroshizuku Kosumosu and Fuyu-Syogun?
The mix was initially an accident, 'some' PIFS got into my PIK sample. I decided to put it all in a pen with a 2mL ink capacity, and added a couple more drops of PIFS to darken PIK (I tend to prefer darker inks). I call this "Fuyu-Mosu #1". The color is not bad, I guess you could say it became a dusty rose. It has a nice dark halo effect. Interestingly, after playing around with the ink a bit, I noticed a very bright green sheen when the ink pools on the paper. It was quite a surprise.
I decided to add more PIFS to see if I could darken the pink more, and maybe get more sheen out of it. I call this "Fuyu-Mosu #2". The color was not as nice, it leaned more purple, which I dislike in my pinks, and could even be called a light burgundy. Anyway, about the sheen, it became duller and less intense.
