Viaduct vs Cloister
Viaduct is a Sherwin-Williams color while Cloister comes from Tikkurila. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. At LRV 50 vs 46, Viaduct will read as the brighter of the two — a 4-point gap that matters most in north-facing or low-light rooms. With a ΔE of 2.9, the difference is subtle — you'd need them side by side 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.
