Start with the documented color character
Rosemary is a deep green cooled by gray. Temperature is a useful description, but neighboring materials can change the impression. Rosemary is deep enough that pairing it with black counters creates a question about the outline between two dark planes.
Why the black counters and pale wood stools relationship matters
Pale wood stools add room-level contrast, but the countertop-to-cabinet join still needs to remain intentional under working lights.
Rosemary has an LRV of 14; Sherwin-Williams Pewter Green SW-6208 is 12. The difference is 2 points, with Rosemary returning more light under the reference measurement. Pewter Green is a deep, cool green rather than a pale sage. This supplies a named color control; the LRV gap alone does not identify the warmer, greener or pinker paint.
Use Pewter Green as a control
Temperature is easier to assess when Rosemary has enough light to show its hue. Check a lit panel beside the actual metal or wood, then inspect the shaded section. A very dark surface may function mainly as an outline even when its published color description has a distinct temperature.
Separate a persistent cast from a comparison effect
Retain a visible boundary between the two dark surfaces or introduce a lighter separating surface. The undertones and neighboring colors covers that related choice.
Judge the temperature description against the full black counters and pale wood stools arrangement. A warm or cool label is a useful starting category; it cannot guarantee that Rosemary agrees with every material assigned the same label. The wood-floor pairing guide covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
