Is dark matter dark because we hav never measured it directly on Earth with the atom?

Well, not quite. The 'Dark' in 'Dark Energy' is precisely this -- it just means we don't know what the heck it is. The 'Dark' in 'Dark Matter' however tells us that whatever it is, it doesn't interact electromagnetically (hence dark).The term dark merely infers that little is known about the two.
