Start with the documented color character
Rain is a cool green-gray with a moderate reflectance value. A physical comparison is needed to decide how that character works with your own finishes. 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
With Rain, identify the hue you want to retain rather than trying to eliminate all undertones. Place the sample with white linen and weathered oak and compare Coastal Plain. A blue-green, rosy or earthy paint may need a different color direction if its defining character is unwelcome.
Separate a persistent cast from a comparison effect
Compare a bluer candidate alongside it; decide which direction suits the existing fabric. The warm-versus-cool comparison covers that related choice.
Keep, compare or change direction
If the unwanted cast remains beside a permanent finish under normal light, that is a practical reason to replace Rain. If it appears only beside an unused sample, remove the comparison and assess the intended palette alone. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
