Benjamin Moore

Mt. Rushmore Rock

AC-39

Mt. Rushmore Rock, also sold as Creekbed (1006), is a mid-tone warm neutral with pink-beige and gray undertones. With an LRV of 32.49, it lands in the medium range, neither overly light nor dark, and reads as a grayed-out taupe with a faint rosy cast depending on the light source.

Part of Benjamin Moore's America's Colors collection, this shade draws from the stone and sandstone tones of the American interior. It works well alongside Linen White (OC-146) for trim, Manchester Tan (HC-81) to echo its warmth, Revere Pewter (HC-172) as a cooler gray partner, and Shaker Beige (HC-45) for tonal continuity.
