Surely tarball comes from tar, which is short for “tape archive”, which has nothing to do with the goo left behind from pyrolysis or with its color. Apparently whoever made this list doesn’t understand the purpose of the tar command :)
(Y’all should really stop conflating tar with asphalt though. The terms are related but not always interchangeable.)
