Hi,

Can anyone point me to someone that makes a black decora timer switch

AFAIK, "Decora" is Leviton. A search of the Leviton site for "decora
black timer" finds no hits. "decora timer" leads to a number of
choices. A very quick perusal found ivory/almond/white, no black.
Sounds like paint-can time.
