  We introduce a new method to construct a Grothendieck category from a given
colored quiver. This is a variant of the construction used to prove that every
partially ordered set arises as the atom spectrum of a Grothendieck category.
Using the new method, we prove that for every finite partially ordered set,
there exists a locally noetherian Grothendieck category such that every nonzero
object contains a compressible subobject and its atom spectrum is isomorphic to
the given partially ordered set.
