Portico vs White Duck
Portico and White Duck come from the same Sherwin-Williams collection. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. The 32-point LRV gap — 74 for White Duck vs 42 for Portico — means White Duck will open up a space more effectively. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 19.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

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.
