Benjamin Moore

River Blue

2057-10

River Blue is a deep teal that approaches near-black saturation, with an LRV of 7.27 indicating very low light reflectance. The blue-green base carries cool undertones that remain visible even at this depth, distinguishing it from a pure dark navy or charcoal. In low light it can read almost black, while direct illumination reveals its teal character.

It pairs with Benjamin Moore Simply White for maximum value contrast, Stonington Gray as a lighter cool-toned companion, Kendall Charcoal for a dark tonal scheme, Seaweed for an analogous green bridge, and Blue Danube for a mid-tone blue extension.
