A method of fabricating a multi-tone glass vessel includes depositing a molten-glass first gob of a first glass color into a mold having a lower end and an upper end. An initial quantity of gas is injected into the mold in order to form a gob cavity within the first gob and cause the first gob to partially inflate and expand toward the upper end of the mold. A molten-glass second gob of a second glass color is deposited into the mold over the partially-inflated first gob. The introduction of a second quantity of gas into the gob cavity within the mold forms the first and second gobs into a single, multi-tone vessel of predetermined shape.
