Intellectual Gray vs Rushing River
Intellectual Gray and Rushing River come from the same Sherwin-Williams collection. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 36 vs 34 — so neither will read significantly brighter or darker than the other. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.1 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Intellectual Gray vs Rushing River in Real Spaces
1 real room side by side. Intellectual Gray and Rushing River are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
