About Dutch Boy Whale's Tail
With an LRV of 16, Whale's Tail is a deep, dramatic shade. It soaks up light in north-facing rooms and looks richest where strong daylight hits it. Its teal undertone is the part to watch: it gets picked up by whatever sits next to it, so test it against your trim, floor and the room's main light before committing. Warm artificial light softens it; cool LED can make it look flat, so match your bulbs to the mood you want.
Whale's Tail works best as a feature — a single wall, built-ins, a study or dining room — rather than wrapping a whole bright space. Grays like this read as a modern neutral and sit comfortably alongside both warm woods and cool metals.
