In the pot, Ultramarine Blue reads as a cool blue, dark and moderate. Matching it is straightforward: Citadel Alaitoc Blue lands at 92 percent in the same finish, and 3 brands in all carry a close same-finish swap. For modelling, drop to Cultist Purple in the recesses and step up to Stratos Blue on the edges, both The Army Painter paints. Bottom line: run out mid-project and another brand will get you within a shade.
