Robert Oster Sepia Nights is a deep walnut brown with a quiet purple undertone. It is darker and cooler than traditional golden sepia, giving the page an archival mood without looking artificially antique.

Independent testing finds low shading, no sheen, no shimmer, and average flow. It behaves well on fountain-pen-friendly paper and is comparatively restrained: the interest comes from the unusual purple-brown base rather than special effects.
