The decision for this particular color
Alabaster can be considered for exterior if its color and depth suit the space; confirm exterior product, tint and substrate compatibility separately. Alabaster OC-129 has a pink-white identity that should not inherit the warm-white advice written for SW-7008.
Why the pink-beige stone and ivory fabric relationship matters
Pink-beige stone offers a reason to consider that blush, but the authentic Benjamin Moore sample must establish the actual relationship.
Alabaster has an LRV of 85.08; Sherwin-Williams Alabaster SW-7008 is 82. The difference is 3.08 points, with Alabaster returning more light under the reference measurement.
Read the facade in sun and shade
Check Alabaster against the factory window white and the roof in open daylight, then under an eave. Exterior sun can make a light sample appear quite different from the same board indoors. Decide whether the trim-to-siding boundary should remain visible from the street.
Confirm the coating after the color direction
Specify OC-129 on the sample and judge its pink note; do not transfer advice about SW-7008. The coordinating color options covers that related choice.
Alabaster is being assessed here as a color, not as a complete exterior product specification. Ask the supplier to confirm tint availability, substrate suitability and any restrictions for the intended coating. For factory-finished or vinyl materials, follow the relevant manufacturer requirements rather than choosing solely from a reflectance value. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
