Anyone care to venture a guess as to how long a solution of dye in methanol can be kept in the dark?

Bill - I'm sure it depends on your dyes.
Anyway, I'd try using glass bottles with teflon lined caps to give maximum life.

It depends on dye and bottle as well as temperature. The colder you keep it the longer it keeps. The dye should also be protected from light.
