What Color Is Blue Monday, Really?
Blue Monday reads as a cool blue-green tone — dark — high drama, needs strong daylight or warm bulbs. The notes below cover how Dunn-Edwards DET568 behaves in different light and the closest matches at competing US brands.
Best Rooms and Uses for Blue Monday
Blue Monday works best as a feature — a single wall, built-ins, a study or dining room — rather than wrapping a whole bright space. Blues calm a room, which makes them popular in bedrooms, bathrooms and home offices.
How Lighting Changes Blue Monday
With an LRV of 18, Blue Monday 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.
Most complaints about Blue Monday are a light mismatch. Upload a photo of your actual room and see it on your walls — then ask for the same wall in north light or evening lamps before you buy a single sample.
