To choose a contrast trim color with Alabaster walls, select a soft neutral like putty, greige, or blue-gray that is about fifteen to twenty LRV points darker than Alabaster's LRV of around eighty-two. This subtle contrast avoids harsh clashes and complements Alabaster’s warm undertones. Always test your chosen trim color under your room’s actual lighting and against your wood floors before painting. This method ensures the trim adds depth without making the walls look yellow or icy, keeping your space balanced and polished.
