Yes, Dektol tends to be light brown, like others have said. And D76 is
definitely a film dev - and I've never seen it sold in anything other
than single packs of powder. Dektol will oxidize rather quickly
compared to the Ilford/Agfa paper devs in my experience but sometimes
yields rather more sublte results w/fiber-based paper...espec as it
heads towards its exhaustion point. Many times I will stop and store my
dev at around the 50% of recommended capacity, and use that in next
session mixed w/fresh batch. This helped take out the overly stark
"snap" one sometimes gets from absolutely fresh paper dev.
