Curio Gray vs Sycamore Tan
Both from Sherwin-Williams's palette. Curio Gray reads as greige-grey, while Sycamore Tan reads as beige-greige — two distinct hue families, not close cousins. They have nearly identical light reflectance values (26 vs 27), so they'll read as similarly Medium in most lighting conditions. Both lean warm, so they'll behave similarly in mixed or changing light conditions. At ΔE 1.5, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Curio Gray vs Sycamore Tan in Real Spaces
1 real room side by side. Curio Gray and Sycamore Tan 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.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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.
