Are you only looking for material that would have originally been shown on Television?
Otherwise (and already suggested) there's tons of restored Technicolor films from the 30's & 40's on Bluray, Wizard of Oz, Robin Hood, Meet me in St Louis...
Many of them would have been shown on TV too at some point in time.
I would also suggest the Walt Disney's Treasures series of DVD's.
