Opal Silk vs Rhine River
Where Opal Silk belongs to Behr's range, Rhine River is a Benjamin Moore color. Opal Silk reads as blue-green, while Rhine River reads as blue-grey — two distinct hue families, not close cousins. Rhine River (LRV 47) reflects noticeably more light than Opal Silk (LRV 43), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Opal Silk runs green while Rhine River is decidedly green and blue, which means they'll respond very differently to warm vs cool light sources. At ΔE 2.4, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
