Start with the documented color character
Rain is a cool green-gray with a moderate reflectance value. Temperature is a useful description, but neighboring materials can change the impression. Rain is a cool green-gray whose weather name does not establish how blue the finished room will appear.
Why the white linen and weathered oak relationship matters
White linen and weathered oak create a restrained setting in which a bluer control can clarify the desired color direction.
Rain has an LRV of 49; Sherwin-Williams Coastal Plain SW-6192 is 37. The difference is 12 points, with Rain returning more light under the reference measurement. Coastal Plain is a cool green with a midtone reflectance value. This supplies a named color control; the LRV gap alone does not identify the warmer, greener or pinker paint.
Use Coastal Plain as a control
Use a warmer and a cooler object already in the room to assess Rain, keeping their real proportions visible. The target is a coherent relationship with white linen and weathered oak. Do not assume that every blue behaves alike or that all greens belong on the same side of a temperature label.
Separate a persistent cast from a comparison effect
Compare a bluer candidate alongside it; decide which direction suits the existing fabric. The undertones and neighboring colors covers that related choice.
Keep, compare or change direction
Judge the temperature description against the full white linen and weathered oak arrangement. A warm or cool label is a useful starting category; it cannot guarantee that Rain 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.
