Rhine River vs Celestial Blue
Where Rhine River belongs to Benjamin Moore's range, Celestial Blue is a Little Greene color. Rhine River reads as blue-grey, while Celestial Blue reads as blue-green — two distinct hue families, not close cousins. Rhine River (LRV 47) reflects noticeably more light than Celestial Blue (LRV 44), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Rhine River runs green and blue while Celestial Blue is decidedly green, which means they'll respond very differently to warm vs cool light sources. At ΔE 2.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
