Obviously we're not consistent in portraying the Neathbow visually and often when we do we try to portray neath-colored things as having gradients or iridescences that suggest the color being more than a color, but this is kind of what comes to mind:
- Peligin: A black ink with a bluish shimmer: Diamine Tempest
- Violant: A heavily sheening purple/blue ink: Diamine Polar Glow
- Apocyan: A true teal tone with some shading: Iroshizuku Syo-Ro ('dew on pine')
- Viric: A bright chartreuse: Iroshizuku Chiku-rin ('bamboo forest')
- Cosmogone: A very bright orange-yellow: Diamine Sunrise
- Irrigo: A purple-black ink with some shading: Lamy Dark Lilac
- Gant: A warm grey; Iroshizuku Kiri-Same ('autumn shower')
(there's an alternate version of this list which is just very aggressively sheening/shimmering inks that get at that 'more than a color' idea, but I figure it'd be cuter to have a mix of reasonable and unreasonable inks)
