Rain and Coastal Plain: the documented difference
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. Choose by the material relationship as well as the number. Rain is a cool green-gray whose weather name does not establish how blue the finished room will appear. Coastal Plain is a cool green with a midtone reflectance value.

The choice beside white linen and weathered oak
White linen and weathered oak create a restrained setting in which a bluer control can clarify the desired color direction.
Set up both candidates with white linen and weathered oak. Use equal-sized boards with the intended finishes and place them in the same orientation. Do not put one directly beside a window and leave the other in shadow. A difference that follows the position rather than the board is a lighting observation, not evidence that the formula changed.
What the comparison can—and cannot—settle
For a second point of reference, Quietude is recorded at LRV 48. The undertones and neighboring colors covers that related choice.
Compare a bluer candidate alongside it; decide which direction suits the existing fabric. Assess Rain and Coastal Plain alone as well as side by side. The unchosen board will not remain in the finished room, and a preference created only by that neighbor may not survive its removal. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
