Night Owl vs River Rock

Both from Benjamin Moore's palette. Both sit in the beige-greige family, which is useful context if you're narrowing within a single hue direction. Night Owl (LRV 10) reflects noticeably more light than River Rock (LRV 7), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Both lean yellow, so they'll behave similarly in mixed or changing light conditions. The ΔE 8.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
