For me, that was Noodler's Black Swan in Australian Roses. It looked so cool and full of shading in the swatches I looked at - especially when it got dark, nearly black where it pooled.
Maybe I got another, worse batch of it or something, but for me it's just a really uniform magenta, even on TR and wet pens. I don't get what the hype is about, but maybe I was just unlucky.
Funnily, for me, skull and roses sheens red pretty heavily on nearly all papers. Maybe you got a bad batch, as well?
