Sailor's new Dual Shading Manyo inks left some people confused, the packaging looks incredibly similar to previously released Sailor Manyo colors. Primarily Nekoyanagi/Fuji and Haha/Hinoki. Here are some swatches to help clear the confusion. The inks actually are not very similar on the page at all.
Sailor Nekoyanagi primarily writes as a light purple and slightly sheens into a green color. This ink is very soft and not the most legible on the page with finer nib sizes.
The new Fuji color is comparatively a much deeper purple than Nekoyanagi and looks to have a little grey in it as well. It sheens to green, but also sheens the slightest bit to blue.
