Confusion in word usage.

'inherit' *never* appears at the specified or later level - it's
*solely* a cascaded-time value.  It turns into the parent's computed
value at specified-value time.  (Or maybe I'm misremembering what we
intend to define in Cascade, and it sticks around to specified-time,
but is guaranteed to disappear at computed-time. Whatever, doesn't
change my point.)

Point is, computed value of 'color' is always a real color. If the
specified value is "currentColor", then it computes to its parent's
computed 'color' value, *the same as if the specified/whatever value
was "inherit"*.  (Doing it this way means we get the full suite of
inherit behaviors for free, such as working properly on the root,
