Benjamin Moore

Seaside Blue

2054-50

Seaside Blue is a mid-range cornflower blue with an LRV of 47.43, situating it at a moderate reflectance level that neither dominates nor recedes on a wall. Its undertone is cleanly cool with a slight aqua lean that separates it from truer periwinkle shades. In rooms with warm lighting, the blue reads softer and slightly muted.

Benjamin Moore White Dove and Classic Gray pair well as trim colors that temper its coolness. Hale Navy deepens the blue story, while Palladian Blue and Wythe Blue create a tonal gradient across adjacent surfaces.
